Arsenal supporters reacted furiously to Joel Campbell's substitution during the Gunners' 2-1 defeat by Swansea City last night.

Loud boos could be heard from the home crowd when Campbell, who had put Arsenal ahead in the game, was taken off in the 64th minute, 10 minutes before Ashley Williams knocked in the Swans' winner.

Attempting to explain his actions, Wenger said after the game:

"Campbell hasn’t played for a while and he started to tire," he said.

"He played against a very young left back and I thought Welbeck could give him some problems with his runs in behind.

"These kinds of decisions don’t mean that Campbell did badly. I think he did quite well tonight.

"I also think that there was room on that flank to be very dangerous."

The defeat was yet another serious dent in the Gunners' Premier League title ambitions. They are now six points behind leaders Leicester City with 10 games still to play.
