Might be on my own but this is a boring deadline day, money's ruined the game.

I know the cost of living and inflation are high, but some of these fees banded around today are just ridiculous.

Former Sunderland striker Marco Gabbiadini on Sunderland's deal for Kevin Danso:
"I think they are sensible signings."
"They're not going to make the blood rush through the veins of Sunderland supporters as far as attacking options or how dynamic they are but you need players like this to build your team around so that the Enzo Le Fees and the [Chris] Riggs and the [Noah] Sadikis can go and be a little bit more expansive."
"So, yes, another solid signing which we've made quite a number of those over the last couple of years."

The Wearside club will have a £22.5m obligation to buy fee if Regis Le Bris' side stay in the Premier League.
The 27-year-old has not featured in the Premier League this season under Roberto de Zerbi, but he scored in his League Cup appearance against Charlton Athletic.

Chelsea continue to have a scattergun approach to their transfers, and many will have an underwhelming impact. However, the signings of Rogers and Martinez are going to be gamechangers for us, expect us to be solidly in the Top 4 and hopefully pushing Arsenal for the title!

Chelsea goalkeeper Robert Sanchez has completed a season-long loan to Como.
Sanchez started Chelsea's opening Premier League game at Fulham but wasn't named in the squad in Sunday's win over Brighton with Emi Martinez joining from Aston Villa.
Earlier we brought you the news that Chelsea goalkeeper Robert Sanchez was undergoing a medical at Italian side Como.
Well, we have some news on that front...

Image source, Getty ImagesFulham are in advanced talks to sign David Affengruber from Elche, but with work still to be done.
The Austria international, 25, is keen on a move to Craven Cottage where officials are confident of completing a move before Tuesday's deadline.
It would be the third potential addition of the day, alongside two midfielders - Eintracht Frankfurt's Hugo Larsson and Real Madrid's Miguel Angel, who have both been completing medicals in London.
They are also looking at potentially adding a right-back before the deadline.
Clubs sometimes conclude deals at the last minute and it is not always easy for them to get everything completed and sent over by the deadline.
The deal sheet allows a club to confirm that a deal has been reached in order to allow for additional time to submit the remaining documentation.
For a deadline of 23:00, the deal sheet cannot be used before 21:00 and needs to arrive fully completed before the transfer window closes.
Once the sheet arrives, clubs have got another two hours, or until 01:00, in which to submit the full paperwork.
Image source, Getty ImagesWAHHHH.
This is your three-hour klaxon.
The Premier League transfer window will shut in three hours time. There's still plenty of time for those last-minute deals to get over the line. And of course still time to get a deal sheet prepped...

Image source, Getty ImagesNottingham Forest defender Zach Abbott has signed a new contract and joined Southampton on a season-long loan.
He has signed a four-year deal at the City Ground after a breakthrough season, which saw him make his Premier League debut and play seven times in the Europa League.
The 20-year-old made his senior debut against Newcastle in the Carabao Cup in 2024 and has made 12 appearances in all competitions.
Abbott, who has come through the club's academy, said: “I had memorable experiences last year that have given me even more hunger to improve and continue my development.
"This club has been my home for nearly 10 years, and I have a big sense of pride every time I pull on the shirt."
Image source, Getty ImagesChelsea have confirmed Dario Essugo will join Ligue 1 RC Strasbourg on loan and that Deivid Washington will join the French side on a permanent transfer.
Essugo joined Stamford Bridge in June 2025 for a £18.5m fee. Last season, the midfielder featured in five games for the Blues.
Washington joined Chelsea in August 2023 for a fee worth £17.2m, but has only featured in three senior games for the west London club.

I have a feeling Spurs are going to announce a big signing before the window is up. Something tells me they won't be happy losing out on Ndiaye and Gakpo...
Taz
Not loads going on here, is there?
Remember we're still waiting for updates on Jack Grealish's return to Everton, confirmation of Iliman Ndiaye's move to Manchester City and Enzo Fernandez's switch from Chelsea to City.
Could there be a big last-minute transfer that catches us all off guard?
It kind of doesn't feel like it's coming but you never know.
Someone get tracking some flights or something...

Image source, Getty ImagesNottingham Forest defender Morato has joined side West Ham on a season-long loan, with the option to make the deal permanent.
The 25-year-old reunites with former Forest boss Nuno Espirito Santo at the London Stadium.
The Hammers had been interested in Wolves' Ladislav Krejci but the Czechia international does not want to move to another Championship club, with Wolves unwilling to sell to a promotion rival.
Morato joined Forest from Benfica in 2024 and made 66 appearances in all competitions.
The defender was named in the team of the tournament for the 2025-26 Europa League and played in all but two games in the competition as Forest reached the last four.

Image source, Getty ImagesArsenal have confirmed Ethan Nwaneri will join Borussia Dortmund on a season-long loan for the rest of the 2026-27 season.
The 19-year-old spent part of last season on loan at Ligue 1 side Marseille.
Nwaneri became the youngest player in Premier League history when he came off the bench for Arsenal aged 15 years and 181 days in 2022.

Image source, Getty ImagesLeeds United are exploring a move for Eintracht Frankfurt winger Jean-Matteo Bahoya.
It follows the collapse of the 21-year-old's proposed move to Hull City over concerns about a switch to the East Yorkshire club.
However, with time running out before the transfer deadline, Bahoya is now considering a move to Yorkshire rivals Leeds.
Leeds had been interested in signing Chelsea winger Mykhailo Mudryk, but the Ukraine international has instead opted to join Tottenham.

I think Liverpool have made great signings. What's crazy is that they still look light. I still think they need a DM, a new RB and another CB. But those things clearly aren't happening and they've spent plenty enough money. I think they'll just have to wait until next window.
Harry
So, another transfer window is ending without Liverpool buying a midfielder. Curtis Jones sold and Harvey Elliot loaned out. This has disturbing echoes of 2020 when we sold a centre-back and didn’t replace him - that didn’t end well.
