Arsenal boss Arsene Wenger was disappointed with Wojciech Szczesny's clanger in victory over Southampton.

The Pole's blunder was the one blemish on an outstanding performance by Arsenal.

"I think he was disappointed," Wenger said. "That was the negative of the day, that we conceded a goal.

"We can dwell over that but you have to concede at some time, but it happened like it happened."
