But, as per EFL and Premier League rules, Chelsea can be given until 1am to complete the deal - providing that the club have submitted a 'Deal Sheet'.

These sheets provide details of the impending transfer and confirm that an agreement has been reached, before providing clubs with extra time in which to submit all the required documentation.

The details required on this sheet are fairly basic and amount to the clubs and player involved and the fee being paid, if there is one.

Deal sheets cannot be requested until 9pm on transfer deadline day and then must be submitted, fully completed, by 11pm.

Once received and approved by the Premier League or EFL, clubs can then be granted permission to submit all the required transfer paperwork by a 1am deadline.

It is likely that, with time running out in the window, Chelsea will have to submit such a sheet to finalise the addition of Niguez.

Clubs will also be able to sign free agents after today’s window closes.
