Arsenal has completed the £27 million transfer of Brighton attacker Leandro Trossard.

Leandro Trossard, a Brighton attacker, has joined Arsenal for £27 million.

The Gunners will pay an initial £20 million upfront, with an additional £7 million in add-ons.

Arsenal said in a statement that they have submitted all registration documents and “hope” Trossard will be available to play against Manchester United on Super Sunday.

The 28-year-old has agreed to a four-and-a-half-year contract extension with an option for another year.

“They told me they really like me as a player, that I would suit the system and how they want to play,” Trossard told Arsenal’s official website.

“It helps that I’m versatile and can play in a variety of positions. They are excited to collaborate with me, and I am excited to collaborate with them. I’m very excited to work with them, and I believe Mikel [Arteta] is an excellent coach.

“I prefer to play in the pocket behind the striker. On the wings, I can also explore myself. I’m comfortable in either position, but if I had to pick one, it would be behind the striker – but it all depends on the system.

“This has been my best season in the Premier League until now. We did an excellent job in Brighton, and my grades have been excellent. Obviously, due to my situation [at Brighton], I haven’t played much since the World Cup, but I’m so excited to start at Arsenal and prove myself at a top club to help the team.”

Arsenal pursued the Belgian international after Chelsea signed Mykhailo Mudryk from Shakhtar Donetsk on January 15.

“It was a difficult situation because I knew he wanted to leave. I’m sorry for the last period, because I preferred [to play] players who were consistent and did not exhibit any unusual behaviors.

“We’ll see if we can replace him. We’re a good team regardless, and we can play well with or without Leo.

“I believe that you can always improve and bring in new players during the transfer window. But we have a good XI now, and the players in the squad are all very good. It is difficult to improve.

“We will do something if Tony [Bloom] and the club have the opportunity to improve the squad.”
