“I think him being at Manchester City was fantastic, but this had to happen.
“He had to fly the nest, and Arsenal is an amazing club.
“Unfortunately, he didn’t join a club that I love in Everton with all the speculation, but at Arsenal he’s doing an amazing job.
“He has the attributes to first change the culture, what the club is about and the brand of football, and you can already see how the players are taking to that.
“It’ll take time as at City he was flying, but I’m looking forward to seeing how he’ll flourish because he’s there for the long term.”
