Arsenal boss Arsene Wenger admits recent results has knocked their confidence.

Wenger has admitted that Arsenal have been psychologically affected by their first significant wobble of the season but is adamant that the "unbelievable focus" of his players will ensure they get through this period.

"I feel we were a bit edgy because we conceded six at Man City and that played in our heads at the start," said Wenger. "In the second half we took control of the game and had two or three chances where we could have done better, but the games we played at Napoli and City had a little weight in our heads."

Arsenal have also lost this season against Manchester United and, asked if there was a mental issue against the best teams, Wenger said: "I don't know if it's linked to the fact we've played the big sides. You question us. The last result at City played a part. We had the best defence in the league and, suddenly, we gave six goals away. So the defence wants reassurance. That's natural you'll have an edgy start."
