Arsenal boss Mikel Arteta was delighted with Leandro Trossard after victory over Leeds.
Arteta was asked later if in his wildest dreams he could have imagined Trossard playing so well.
He replied: "I have very wild dreams! No, seriously, we knew about his quality and what he could bring to the team.
"We are really pleased with him, he can play on the right, he can play on the left, he can play as an attacking midfielder, as a nine, a false nine.
"He's really contributing to the team and he really takes a lot of responsibility in games to make things happen and we love that."
