Leandro Trossard vows to help Arsenal achieve their "dreams" after joining from Brighton

Arsenal have confirmed the signing of Leandro Trossard from Brighton, with the 28-year-old becoming the Gunners' first incoming of the January transfer window.

The Belgian international has played in the Premier League for the Seagulls for three-and-a-half years, scoring 25 goals in that time. He has signed a long-term contract with the Gunners.

Speaking to the club's official website, Gunners boss Mikel Arteta said: "It is good work from everyone at the club to complete the signing of Leandro. He is a versatile player with high technical ability, intelligence and a great deal of experience in the Premier League and at international level.

"Leandro strengthens our squad as we head into the second half of the season and we're all looking forward to working with him. We welcome Leandro and his family to Arsenal Football Club."

Trossard's first comments after Arsenal signing

In his first club interview as a Gunners player, Trossard said: "This is a big club and I'm ready to show the fans what I can do. Everyone has seen how well we're doing already and I'm here to help achieve their dreams - including myself.

"I'm going to take it day by day, work hard and try to help the team to achieve their goals. [I want to] get better as well.

"I know the manager is a great coach and I hope to be involved in doing great things and getting better as a player in every aspect.

"I'm really excited to see the fans in the stadium. I hope I can give you my all. I want to try and create as many magic moments as possible, and hopefully we can celebrate together."

He went on to add: "[The club] has so much history and I want to be part of that history going on. That's why I joined this project. I'm really excited to be here. I want to show myself to all the fans and on the biggest stage."

Arsenal have announced that they are hopeful Trossard will be eligible for Sunday's Premier League clash against Manchester United, as all paperwork has been submitted.

If he is not able to play in that fixture, he could make his debut in Arsenal's FA Cup fourth round tie at Manchester City on January 27. He did not feature in Brighton's third round match in the competition, therefore is not cup-tied.
