Arsene Wenger has finally admitted his regret at not leaving Arsenal sooner than 2018.

The Frenchman is the subject of a new documentary titled Arsene Wenger: Invincible which focuses on his 22-year stint with the north London club.

During his reign he became the most successful head coach in the club’s history, landing three Premier League titles – including the memorable 2003-04 Invincibles campaign – and seven FA Cup triumphs.

However, his last few years at the club turned sour, with fans ultimately turning on him for what they perceived to be underachievement – despite consecutive seasons of Champions League qualification.

Wenger has previously described his final few months at the club as ‘like a funeral’, while other club legends, such as Dennis Bergkamp, have suggested he should have taken the leap to leave the Emirates sooner than 2018.

Now, for the first time, the 72-year-old has admitted that he was wrong to stay in situe at the club for as long as he did.

‘I identified myself completely with the club – that was the mistake I made,’ said Wenger – as per the Telegraph. ‘My fatal flaw is I love too much where I am … where I was. I regret it. I should have gone somewhere else.’
