Writing for The Sun, Redknapp declared: "In my eyes the Premier League is over already, certainly in terms of who will be champions.
"So much for my view that six or seven teams could still be in with a shout come late April.
"As far as I'm concerned, the only battle now is for second place. And the way City are going, a poor second at that.
"Since I said we were in for a 1970s-style season, when you could throw your hat over half a dozen teams, City haven't dropped a point.
"In fact they've only conceded one goal — two if you include the FA Cup at Cheltenham — while everyone else has stumbled at some stage.
"That's a real pity, because we'd all have loved to be on the edge of our seats going into the last fortnight.
"But this race is over, believe me."
