The PL is too competitive these days.
Back in the day there was only one serious contender and Wenger's fitness techniques and knowledge of the overseas game - and a bit of steel from the old guard - helped lift us above them for a while.
I don't think Wenger is as bad as many on here claim, but he's not good enough to win a PL title.
Maybe with City's current squad which is on a different planet to everyone this year but that is unusual.
He certainly wouldn't win it with Utd's squad.
