Wenger said: “It was an exceptional game, played at an exceptional pace.
“There were patches of total football in there, undoubtedly one of our best performances of the season.
“But, having missed all those chances and then suffered the disappointment of Bolton coming back, I thought my young players showed amazing mental strength to win the game.
“I am so proud of them because they proved they had fighting spirit, as well as excellent composure on the ball.
“We don’t have much time to prepare for the next game, so the fatigue factor is important.
“Hopefully, the players can recover but I will make a few changes for Saturday, that is for sure.”
