Arsenal boss Mikel Arteta is delighted with the form this season of Leandro Trossard.
Arteta was asked at his Champions League presser if he was his best signing.
He replied: "I'm not a financial advisor or the economist of the club but he is a tremendous player who has great talent and great intelligence to play the way we want to play. He is a really good fit for us.
'That was one of the main reasons why we signed him. First of all he has experience of the league and did what he had done in the league already. In January we had a lot of issues in the front line and he could cover those necessities in a really efficient way.
"He has proven he can do that."
