If we sell him now then we'll never get back to the top. The whole point of buying youth is to craft the team of the future, not grab a quick profit when they look like quality.
If we turn into a selling club then we really are doomed to eternal mediocrity. For me this could be one of the most telling episodes in our future.
As for Walcott, is he really that much better than Sterling even at this stage?
Oh come on.. Walcott is currently a much better player, he has more experiences in the league, champions league and at international level, not too mention Walcott scores more. Sterling is still very raw and Walcott is more like the finished article (currently).
I've no doubt that Sterling can be a better player in the future but not by moving to a club where he won't play regularly (as he does here), that is what has stinted Walcott's progression and will do Oxlade Chamberlain no good either. Sterling needs to stay at Liverpool (unless guaranteed regular first team football elsewhere) and we need him to stay.
