The transfer deadline might be set for 11pm, but clubs may have until 1am to get their deals done.

It is all about the deal sheet.

A deal sheet is used when clubs reckon they might be struggling to get all the details sewn up on deadline.

In effect, it sends the transfer into extra time.

A deal sheet can be submitted to the Premier League between 9pm and 11pm.

It's a simple form which sets out the name of the player, the two clubs and the financial terms of the proposed transfer.

Once the deal sheet has been submitted, clubs have two hours to complete the transfer.

Such is the way that some deals work, it might be Wednesday morning before the clubs make the announcement - but they do have to have been wrapped up by 1am at the latest.

Last summer, Manchester City did not confirm the signing of Gianluigi Donnarumma from Paris St-Germain until the morning after the window closed.

We've seen a decent bit of cash thrown around in the Premier League this summer but those of you who are bothered, here's a breakdown of the biggest spenders.

If lower league transfers are your vibe, then the EFL live text is the place for you.

Two deals in the last hour or so have seen Championship players go to France on loan.

West Ham defender Jean-Clair Todibo is moving to Lens and striker Cameron Archer is going from Southampton to Auxerre.

Chelsea are playing down the need to sign a replacement before Tuesday's transfer deadline despite the sale of Enzo Fernandez to Manchester City.

Following the departure of the 25-year-old Argentina international, Chelsea can point to more than £425m raised through player sales, including add-ons. Loan fees are expected to take that figure closer to £500m.

The club explored moves for Roma midfielder Manu Kone, Monaco's Lamine Camara and another unnamed Premier League player. However, Chelsea felt the £125m fee received for Fernandez could lead to inflated demands in the transfer market.

Chelsea also retain a number of midfield options, including Moises Caicedo, Reece James, Valentin Barco, Romeo Lavia and Jordan Henderson.

Who will Chelsea sign as a replacement?

We might have your answer coming right up...

Enzo Fernandez is a man who costs a pretty penny.

Fernandez has cost £230m in his past two moves and will become the first ever footballer to complete two £100m+ moves. That is a decent bit of money.

However, he brings with him a wealth of top-level experience.

At only 25, Fernandez has already racked up 285 league appearances across the Argentinian, Portuguese and English top-flights, as well as playing 49 times so far for his country.

He has won the World Cup and Copa America with Argentina and major silverware in every country he has played - most recently winning the Club World Cup with Chelsea in 2025.

Chelsea

The departure of Enzo Fernandez to Manchester City begs the question, who will replace him at Chelsea?

The Argentine midfielder came on as a substitute in Chelsea's opening game against Fulham but has not been included in Xabi Alonso's squad for their next two games.

Will Chelsea need to do some last-minute business to replace their captain? Some reports are suggesting Chelsea have moved for Monaco midfielder Lamine Camara.

Who would you like to see come in, Blues fans?

BBC Radio 5 Live's Monday Night Club discussed Manchester City's late move for Chelsea's £125m-rated Enzo Fernandez, despite already signing midfielders Elliot Anderson and Ayyoub Bouaddi this summer.

Former Premier League striker Chris Sutton added: "It is about having the strongest squad to give them the best possible chance of challenging. The money really doesn't matter."

Former Liverpool defender Stephen Warnock agreed, stating: "If your director of football is saying 'I can give you this player' then you don't need to care about the fee.

"The fee is irrelevant as long as the club has agreed to get the player through the door."

Enzo Maresca said he would make a decision on his leadership group at Manchester City when the transfer window had closed.

The Italian boss made Enzo Fernandez captain at Chelsea and it's likely his leadership qualities have played a large part in Maresca's desire to get this deal over the line.

City's current captains are defender Ruben Dias and striker Erling Haaland. Will Fernandez come in as the main man?

As it stands Premier League clubs are just £13m away from breaking the all-time summer transfer record.

English top-flight clubs have already pushed beyond the £3bn barrier with spending close to breaking the record of £3.14bn from 12 months ago.

Four of the 11 most expensive signings in the history of football have happened this summer – with three of them being Premier League signings.

Chelsea's £117m signing of Morgan Rogers from Aston Villa and Manchester City's £116m spend on Nottingham Forest midfielder Elliot Anderson are the two most expensive British players ever.

And Liverpool paid an initial £106m, which could rise to £123m, for Paris St-Germain and France forward Bradley Barcola.

It looks like that record could be smashed before tonight's 23:00 BST deadline with Enzo Fernandez's move to City taking spending way over the record.

Manchester City

We know that new Manchester City boss Enzo Maresca has been very keen on reuniting with his former Chelsea player Enzo Fernandez.

Chelsea set a deadline for clubs to sign the Argentine several weeks ago but the deadline passed with no deal struck.

But it looks like City have finally got their man and they will be hoping the midfielder can go some way to plugging a gap in the middle of the park following the departures of Rodri and Bernardo Silva this summer.

Chelsea and Manchester City have been negotiating the deal for Enzo Fernandez over the past 24 hours and have now reached an agreement.

Fernandez will now undergo a medical ahead of signing a long-term deal at the Etihad Stadium. Personal terms will not be an issue.

Chelsea

Will Chelsea miss Enzo Fernandez? Well, he's not started any of their two Premier League games this season - both ending in Chelsea wins.

But Malo Gusto was forced to start in the middle next to Romeo Lavia in Sunday's win over Brighton, with Moises Caicedo picking up another injury.

Enzo Fernandez is a man who costs a pretty penny.

His transfer to Chelsea from Benfica in 2023 was worth £105m and his latest move to Man City is £20m more than that.

So he's cost £230m in his past two moves.

That's a decent bit of money.

So, that is a joint-British record transfer fee.

It's the same Liverpool paid Newcastle for Alexander Isak on this very day last year.

Manchester City have reached an agreement with Chelsea to sign midfielder Enzo Fernandez, for a fee of £125m.

Is Monaco midfielder Lamine Camara the one to replace Enzo Fernandez - if he is to leave, of course.

Liverpool had been linked with the 22-year-old but it seems like it could be another midfielder heading to West London rather than Merseyside.
