Sure, he's been an improvement recently on the majority of the lst 2 seasons.
Doesn't mean he's been playing well though.
When he starts contributing more to the team as a attacking mid/support striker then running around a lot, fouling players and being offside he'll be playing well.
But thats not going to happen so he needs to be replaced.
The fact that we do look more dangerous with Fellaini in his position says everything about Cahill these days.
And before anyone starts, yes i love the guy for everything he done for this club, has been brilliant for us but his time is passed and 3 times LMA manager of the year needs to open his eyes and see that.
