The 69-year-old left his position as Arsenal’s longest serving manager at the end of last season amid growing frustration at the club’s failure to challenge the Premier League’s and Europe’s elite.
Wenger has now admitted that his health definitely suffered in the final few years at the Emirates and he was relieved to finally escape.
Speaking at an event in France, he said: ‘In life there are some splits that you choose and some that are imposed on you.
‘In this case it was a bit of a mix of the two. Because, at a certain point, the fans need a change. In my last year it was becoming difficult.
‘So it was both a break-up but also a relief for me, because carrying that responsibility for so long, with all the obligations that come with it, it wears you out.
‘It’s extraordinarily difficult. And last year I felt I was beginning to pay the price health-wise.
