Charles Watts and Lyall Thomas report that Leandro Trossard arrived at London Colney this morning to complete his medical and finalise his transfer from Brighton and Hove Albion to Arsenal.

The key deadline is 12pm GMT on Friday, as the winger has to be registered before then if he’s going to make the squad to face Manchester United at the weekend.

The Evening Standard report that Arsenal are pushing to beat that deadline, so Trossard can make his debut in the United clash.

Brighton boss Roberto De Zerbi didn’t deny Trossard’s imminent exit in his press conference on Friday morning, so it seems to be just a matter of time now.

According to various sources, the initial deal will cost Arsenal £20-21m, with add-ons taking the total cost to £26-27m. Trossard is expected to receive around £90,000 a week.

Fabrizio Romano initially broke the news of Arsenal’s advancing talks for Trossard, and he provided further details of the move on his Twitter page.

The initial agreement was reportedly completed in just 24 hours, after the first contact between the parties on Wednesday. Personal terms were also never an issue, with Trossard turning down two other clubs to join Arsenal.

The winger “only wanted to join [the] Gunners”, according to Romano.

In one sense, this transfer will be a reunion, with Arsenal assistant manager Albert Stuibenberg having previously coached Trossard when he was manager of Genk in 2017.

“I personally offered Leo to Arsenal,” Trossard’s agent confirmed on Thursday night. “This is the most beautiful club for him and the football they’re playing suits him perfectly. The deal took 48 hours which shows how much Arsenal wanted him.”

Arsenal fans will now wait anxiously to see if the club beat the midday deadline.
