Arsenal will have until 12pm on Friday, to register Eberechi Eze, if they want him to be eligible for Saturday’s Premier League clash against Leeds United.
The Gunners have moved quickly to snatch Eze from their North London rivals Tottenham Hotspur.
However, the 27-year-old featured for Palace against Fredrikstad in a Europa Conference League playoff yesterday.
After that, he will make the trip across London for his medicals with Arsenal.
If Mikel Arteta wants to include Eze in his matchday squad for their home clash against Leeds, all the necessary processes for the transfer need to be filed by noon tomorrow.
Arsenal opened their league campaign with a 1-0 win at Manchester United and will be looking to build on that against the newly-promoted team at the Emirates.
