i would say that the opening few games he possibly played better for us than he had for Chelsea in quite some time, due to being in a better team. however, when the midfield looked fragile, so has he. Or it's the other way around....On that basis then he should be playing better with us than he did with them then no?
What did they get rid for seems to be the question on my lips
but your second point is another one of note, why get rid.
at the end of the day, he's had good and bad form this season like most of the squad. He seems a good squad player to have, on balance so far.
