Danny Welbeck's move to Chelsea for an undisclosed fee, means the 35-year-old joins a very small list of players to have represented Manchester United, Arsenal and the Blues.
Only Scotland's George Graham has played for the three clubs in his playing career before Welbeck.
Unlike the England international, Graham played for Chelsea first, then Arsenal, followed by a two-year stint at Old Trafford.
Welbeck started his career at the Red Devils before a £16m move to the Emirates in 2014.
A youngster to watch - Max Dowmanpublished at 07:48 BST 5 August

It feels strange to say that a player who has already scored a goal in the Premier League is about to have a breakthrough season - but that is exactly the case for Max Dowman.
He broke the record to become the youngest scorer in league history last season and made his first league start on the final day of last campaign, too.
The attacker is still only 16 years old, and made six appearances in the league last season, but after being given a taste of first-team action is set to be more involved this time around.
Dowman scored in a pre-season friendly win over Girona and going forward is likely to be a legitimate option for manager Mikel Arteta, both on the wing and as a number 10.
Arteta will still protect the highly rated youngster, but this season could be the time we see Dowman in the Arsenal first team on a regular basis.

Christian Norgaard has been left out of Arsenal's squad for the friendly against Real Betis in Dublin as he nears a move to Everton.
Reports suggest that Norgaard is set to move to the Toffees for a fee of around £7m.
The 32-year-old was with the Arsenal squad for their 4-1 win over Girona last week but did not play any part in the match and is now set for a medical with Everton.
Norgaard signed for the Gunners last summer for an initial £10m with the possibility of £5m in add ons.
However he found game time hard to come by and made just seven appearances in the league as Arsenal won the title. His only start of the league campaign came on the final day of last season.
Norgaard's character and experience around the training ground has been repeatedly been praised by Mikel Arteta.
And with the midfielder now into the last year of his contract, the club have decided to sell him.
Arsenal are also moving closer to agreeing a deal for Newcastle midfielder Bruno Guimaraes.

BBC Sport's Newcastle United reporter Ciaran Kelly provided the latest on Arsenal's pursuit of Magpies captain Bruno Guimaraes to BBC Radio 5 Live's Football Daily podcast:
"As far as we understand the clubs are now in formal talks.
"There has been a claim that Newcastle have rejected an opening bid from Arsenal and the player himself is at the training camp in Spain so I think this one is going to run a little while longer.
"Arsenal, as it's been reported, are confident still of signing Guimaraes.
"Whether this turns into an Alexander Isak-style saga, I'm not so sure.
"I think we should have a resolution one way or another far more swiftly than that.
"It feeds into Eddie Howe's wider decision to step down. If Guimaraes is to go then Newcastle will have lost four key players in less than a year. That is a huge rebuilding job for any manager."
Arteta 'enamoured' by Vinicius but winger wants to stay at Realpublished at 08:29 BST 4 August

Vinicius Jr is set to resume contract talks with Real Madrid this week as Premier League champions Arsenal maintain a key interest in the forward.
The Gunners have identified the Brazilian as their priority left-wing target should his contract situation remain unresolved.
But, while the prospect of one of the world's best attackers moving to north London has captured supporters' imagination, there remains a lot of uncertainty about whether the forward is actually available this summer.
That's because Real Madrid and Vinicius Jr's representatives have been in talks over a new contract for the past 18 months. His current deal runs until 2027.
So, with talks set to resume, where do things stand?
Vinicius returned to the club for his first pre-season training session and medical assessment on Monday following his World Cup campaign with Brazil.
Vinicius also wants to remain at the Bernabeu but with his contract expiring next summer, Real risk losing him on a free transfer if no agreement is reached.
There was a similar situation in 2023 when, with his previous contract entering its final year, Vinicius signed a new deal extending his stay until 2027.
Renewal talks have taken place over the past 18 months, but slowed because of disagreements over wages and status within the club.
Mikel Arteta has already made clear that this transfer window is one where he can take Arsenal to another level, and the Gunners boss has become enamoured with the idea of signing Vinicius.
If he did join, it would be a real sign that Arsenal are looking to build on their Premier League title win last season, bringing in one of the best players in the world in the peak years of his career.
Those close to the winger have always played down the immediacy of any move.
Arsenal are also aware that even though their target is in the last year of his deal there is no guarantee they will get their man, and the power lies with the player at this point.

Christos Tzolis showed Arsenal fans a glimpse of what may be to come as he scored on his debut in their pre-season win over Girona.
Signed to replace Leandro Trossard after his transfer to Besiktas, the Greece international made the switch to north London in a £34m transfer from Belgian side Club Brugge.
The 24-year-old skipped beyond defender Arnau Martinez before firing a low effort into the bottom of the net, via the help of a slight deflection, in the 30th minute.
But it was Kai Havertz who slotted Mikel Arteta's side into the lead 14 minutes earlier.
Martinez climbed highest from a Girona corner to halve the deficit four minutes after the half-time break, before Max Dowman reinstated Arsenal's two-goal lead three minutes later.
The flurry of goals was not over there as Gabriel Jesus made it three goals in five minutes to fire the Gunners into a 4-1 lead.
Arteta named a strong starting XI in Spain with Viktor Gyokeres, Havertz and Piero Hincapie each playing 30 minutes after their return from World Cup duty.
Will Arsenal sign Vinicius Jr?published at 14:54 BST 31 July

Sami Mokbel Senior football correspondent
The future of Vinicius Junior and whether the Brazil forward is more likely to join Arsenal or stay at Real Madrid has been the subject of several questions sent in via our Gunners Ask Me Anything form.
Straightforward question, not a straightforward answer.
Before Arsenal can even think about formalising their interest in Vinicius Jr, they need the player to decide his future at the Bernabeu.
The Spanish club have offered him a new contract, buttalks are at an impasse, with neither party willing to budge as it stands.
Real Madrid, of course, want the player to renew. Truth be told, Vini Jr would like to stay.
But given his current deal expires next summer, opening up the prospect of Real losing him for nothing, the La Liga side need a resolution this summer.
If a new contract can't be agreed - that's when Arsenal come in. But the cost of the deal to bring Vini Jr to the Emirates would be one of the most expensive, if not the most expensive, transfers in British football history in terms of a fee and wages.
Internally, the Gunners believe they have the financial means to complete the transfer.
They are also confident the player would join. However, there are still a lot of ifs, buts and maybes to be resolved before Arsenal find themselves in a position to execute a deal they believe they can pull off.

Arsenal 'doing something really special' under Arteta - Szczesnypublished at 11:25 BST 31 July

Former Arsenal goalkeeper Wojciech Szczesny believes Gunners manager Mikel Arteta is "doing a great job" after ending their 22-year Premier League title drought last season.
Their campaign ended on a disappointing note, however, when they lost the Champions League final on penalties to Paris St-Germain in May.
Barcelona goalkeeper Szczesny, who is an Arsenal fan, joined the club as a youth player in 2006 and went on to make 181 appearances across 11 years, lifting the FA Cup twice.
Szczesny said: "I loved it. I think they're doing something really special. It's been the case for the past three years.
"They've come up short a couple of times and last year, they were phenomenal. They definitely won the Premier League and just missed out on the Champions League. So I suffered a little bit of that game.
"It's been a great few years and Mikel is doing a great job. So I'm very happy for them."
The pair were team-mates at Arsenal for five years before Arteta's retirement.
"It's a big relief because I've been an Arsenal fan for 30 years now. So very relieved. I'm very happy for them," Szczesny continued.
"Hopefully, they can repeat that this season. In the Champions League, I do wish them to get to the final, but if they come up against a certain Catalan team, then I won't be supporting them. That would be the first time in my life that I won't support Arsenal."
Szczesny is part of the Barca squad in England to England to face Birmingham City in a pre-season friendly on Friday.
What impact could Saliba injury have on defending champions?published at 09:17 BST 30 July

As defending champions and with an experienced manager, Arsenal are favourites for the Premier League title.
But a lengthy injury to a key starter could affect their title chances.
The club have said defender William Saliba is set to miss an "extended period" after suffering a back injury while at the World Cup with France.
Saliba, 25, made 50 appearances in all competitions for Arsenal last season and his formidable partnership with team-mate Gabriel was a big factor in them conceding fewer goals than anyone else in the division.
Arsenal have a tricky start to the season, facing Aston Villa and Chelsea in two of their first three matches.
Since Saliba's debut in 2022, Arsenal have won 68.7% of their Premier League matches when he has been in the team (131 games).
When he has been sidelined, that win percentage drops to 47.6% (21 games).
