In the week when Roy Keane became the Premier League's latest managerial casualty, Arsène Wenger admitted that he has never felt like walking away from his own job.

On Thursday, a week after questioning his credentials as a manager, Keane resigned from his post at Sunderland. According to his former chairman, Niall Quinn, the Irishman felt he had taken the club as far as he could after 27 months at the helm.

Keane seemed set after Sunderland beat Newcastle in the Tyne and Wear derby in October but a run of six defeats in seven games changed all that. Wenger sympathises with the former Manchester United captain but is highly unlikely to follow Keane's example.

"Have I ever felt like walking away? Not really, no, but you can understand there can be periods when it can be very difficult," said Wenger.

"I don't know why basically he [Keane] resigned. He can explain that to you much better. I just say that when you are passionate and come into the game like that you are hit physically by defeats. He was hit by defeats as a player.

"I am hit physically by defeats, of course. What saves us is that you have a next game. I believe that from looking back you look forward. Basically you move away from your last disappointment into new hope for the future and that allows you to divorce a little bit from the defeat. When you lose consistently you feel it diminishes the belief of the team.

"Do you say to your team 'you are strong, you are good'? But if you don’t win it’s more difficult to convince every time.

“As a manager you go through difficult periods. It’s like life, but just more contracted. In life sometimes you have a happy period of six months and after six months you are less happy. In football it’s a happy period of two days and two days of complete despair.”
