Wenger regrets staying at Arsenal for 22 years
He said that he regretted sacrificing “everything” for the job.
The 68-year-old Frenchman, who was appointed in October, 1996, left the north London club at the end of last season after winning three Premier League titles and seven FA Cups.
In an interview with French outlet, RTL, Wenger said that he would make a decision on his future “in the next few months”.
When asked what the biggest mistake of his career were, Wenger said: “Perhaps, staying at the same club for 22 years.
“I’m someone who likes new things, likes change. But, I also like challenges. I was a little bit of a prisoner to my challenge each time.”
Wenger admitted that he was obsessed with ensuring Arsenal’s success on the pitch, adding that sacrifices in his personal life were one the hardest parts of being a manager.
“I regret having sacrificed everything I did because I realise I’ve hurt a lot of people around me.
“I’ve neglected a lot of people. I’ve neglected my family, I’ve neglected many close ones.
“Deep down though, the obsessed man is selfish in his pursuit of what he loves. He ignores a lot of other things.
“But it’s a bone to chase at the same time,” he added.
Wenger was also confident that former Arsenal players, Thierry Henry and Patrick Vieira, who were now pursuing coaching careers, had the qualities to succeed at the top level.
Vieira recently became Nice coach, while Henry, assistant to Belgium boss, Roberto Martinez, at the World Cup, has quit his Sky Sports punditry role to focus on becoming a manager.
However, Wenger warned the French pair of the sacrifices involved in following a coaching career.
“Often, I’m asked if Thierry Henry and Patrick Vieira will be good managers and I always answer yes,” he said.
“They have all the qualities; they are intelligent, they know football, they have excellent skill sets, but do they want to sacrifice what needs to be sacrificed to do only that?
“It’s an obsession which bounces around your head day and night.”
