Birmingham manager Alex McLeish has tipped Manchester United to win the Premier League despite not having hit top form yet.
The 18-time champions travel to St Andrews on Tuesday hoping to extend their lead at the top of the table.
United beat Sunderland 2-0 on Sunday to go two points clear at the summit with two games in hand on second-place Manchester City.
And McLeish believes United are now firm favourites to win the title come May.
