It was a two-horse race for the title last year as City and Liverpool dominated though Wenger feels the Gunners are now well equipped to put up a fight.
He told BeIN Sports: “Maybe the team who has the potential is Arsenal who could be the closest. Chelsea looks a bit young, not enough maturity up front and not enough maturity at the back. Man Utd hasn't found a settled way where you could say today they could fight for the championship.
“They look quite comfortable the two in front they know they can do it. Man City has a huge technical level where they can always create chances. Liverpool looks very strong at the back and up front they have a midfield that knows its job. Maybe less creative than Man City but they look a little bit in front of the all the others."
