Despite the concerns, the Gunners boss was happy as his team ran out 5-0 winners at the Emirates Stadium thanks to goals from Gabriel and Leandro Trossard, an own goal from Dean Henderson and a double from Gabriel Martinelli.
"The positivity we had right from the beginning," the coach told TNT Sports. "I had a really good feeling in the last 10 days about the team and how they reacted. They are great players, we have a great team and today they really wanted it. I could feel that."
