Totally different striker to Carroll, in fact Andy is unique in his size/build not just for his age but for someone 5 - 10 years older than him.
The lads fucking massive, he can bully defences he could bully most blokes looking at him.
The fact is we don't need to sell David, he's done a job for part of the season. We've now reinforced the striking department, we can afford the lad a little time to develop.
His lack of strength seems to let him down but you can tell by looking at him he's not yet got to fill out into his 'bloke' body, unlike Carroll who looks like he started shaving when he was 10.
And as for United even they get it wrong at times, you can't tell me they weren't kicking themselves watching Spurs trying to jizz 20 plus million over Rossi who they let go for 6 million?
