Gazza M Declan Rice has been our best player this season, the issue isn't him replacing Partey it's that Partey can't stay fit for more than ten minutes. Two bad games in a row doesn't change that.
I'm not going to argue about Havertz as; a) he's been largely rubbish and; b) he's pushed Smith Rowe so far down the pecking order he can't get on the pitch on a day like today when his qualities would have been very useful.
