Arsenal boss Arsene Wenger admits this season's trophyless season has forced him to question himself.

He said: "Of course I looked at myself, it is the first thing I do.

"I worked harder than ever this year.

"Do I have the fire and desire is not what I question. What is so difficult to swallow is that you work as hard as I did and finish empty handed.

"I am not pretentious enough to say I didn't make mistakes - but we only lost three games and we are not competing for the championship."
