Arsenal boss Mikel Arteta was delighted with Leandro Trossard for victory at Fulham.
The Belgian was involved in all three goals for the 3-0 win.
Arteta said, "When we talk about composure and finding the right pass and finding the right colour when it's looking really blurry in the box, he's the opposite. He got three assists and could have scored two.
"I think he was really impressive. Not only that, he had an injury three days ago which could have taken a week, or another 10 days, but he was really willing to come back early and the doctors and medical staff did a lot of good work to get that.
"It makes a big difference in the team. We needed him today and his contribution was superb."
