i don't know whats changed with regards to kuyt but he was amazing under kenny in the previous campaign. I just feel that if the handful of older players currently in the first team aren't going to get a game and aren't cutting it on the pitch then its time to bring the next set of players through. Carra included.
Maybe its too soon to bring Raheem Sterling through, he looked good in his debut even if it was only for a few minutes but he's still very young. So it maybe a good idea to hang onto one of kuyt or maxi. the likes of nathan redmond at birmingham is more or less the same age and but playing first team football so i think sterling should surely get some starts in the europa league at least next year.
I agree with what your saying about adam, he's been poor. so have henderson etc but the difference is they still have time on their hands. at this moment in time though you're right, they aren't good enough. spearing plays a different position so maybe a little harsh. Lucas doesn't score often either in the same position.
