Because I know he won't deliver
I've cut him slack because he's been shit, and if he can deliver ANYTHING I'll be surprised. I've advocated playing him for months because he is a striker and we paid decent money for him. It seems foolish to me that he shouldn't get played when we had no viable alternatives. Sterling has done well, but he doesn't seem to have the strikers knack (the runs in to the 6 yard box, knowing when to run etc[and this isn't me kicking off at sterling] )
The Balotelli comment was after he scored and didn't celebrate. He doesn't owe us as the fans as a majority have been on his back. As long as he turns up and puts in a performance (which he started to do recently) I don't care if he doesn't celebrate.
As for Coutinho, he has given absolutely stupendous performances and he clearly has the ability. Macca has said it in the past and I agree with him, that Coutinho should be pulling the strings against poor opposition, but he doesn't with any degree of consistency.
