It wasn't a criticism, I'm not prepared to judge Borini on the small amount of games he has played for Liverpool on the left of a forward line.
Playing for Liverpool and Sunderland is completely different due to the differing levels of expectation.
Like most others I was keen for Borini to be shipped out in the Summer but considering how poor we have been I'm not against him being given a run out at all and was amazed he didn't play against Middlesborough. At least he will put the effort in!
I agree on the cup game, I think he should have played if he's going to be our 3rd choice striker as it appears he is. Would give him a full run out against a weaker side that would hopefully bring a performance to boost confidence, or at least a good viewing as to what he can do.
In my personal opinion much can be gleamed from his time at other clubs despite the step up in expectation. Though such an approach is definitely not a science and opinions formed from more than just how he has played for Liverpool aren't always correct, on the whole I'm pretty confident that his contribution is going to be pretty limited. The thing I dislike most about him is that he doesn't stretch the game enough (neither does Balotelli but he has other attributes), Liverpool rely on forwards that make clever runs and take up positions that stretch opposition defence, and despite that not happening with anyone at the moment as our team looks a shambles, I've not seen it from borini even when he was playing in Italy.
