Waching daily Jan 31 2019

 Transfer deadline day is expected to bring the inevitable storm of drama, near-misses and nail-biting last-gasp deals

 However, once the deadline passes, several transfers could still be allowed to take place if clubs submit a deal sheet

  TRANSFER NEWS LIVE - UPDATES AND LATEST FROM YOUR CLUB ON DEADLINE DAY  Long after Jim White has left your screen, transfers could be pushed through

 But what is a deal sheet and how can clubs acquire a deadline extension? Express Sport have rounded up everything you need to know

What is a deal sheet? Transfer deals continue to grow in complexity and paperwork with a long list of fine details and terms that must be agonised over before Player X is unveiled to his new fans

 The deal sheet allows clubs to confirm that a deal has been agreed between all parties including the most essential details

 Teams must confirm the name of the player, both clubs involved in the transition and a brief breakdown of the finances

When can a deal sheet be used? The sheet is only available in the final two hours of the transfer window and must be fully completed and submitted to the FA before the official deadline

 Once the deal sheet is approved by the FA, teams have an additional two hours to process every aspect of the transfer

 This usually involves a surge of administrative work to be completed by club officials

 If all information is handed to the FA by the end of the extension, the deal will be completed

 If not, the player cannot be registered to play for his new team until the next transfer window

 This was the case when Adrien Silva's move from Sporting CP to Leicester missed the extended deadline by 14 seconds in 2017

When does the January transfer window close for English and Scottish teams? Teams playing in the English leagues have until 11pm tonight to complete their transfer dealings

 Clubs will be able to apply for a short extension if they submit all relevant paperwork before the 11pm deadline

 Loan deals must be completed in the same timeframe as permanent transfers though free agents can be acquired outside of the window

 All professional clubs in England and Scotland must adhere to the same rules to ensure a level playing field
