I've been saying all season that the Premiership is fairly weak this season.
But Schalke would struggle to stay up in the Premiership, and they've reached the semi-finals of the Champions League.
They beat last year's winners 5-2! In their own stadium!
And yet United looked more convincing against them than they have against any domestic opposition all season.
A United team that most agree is one of Ferguson's weakest.
What does all that say for the state of European football?
