He was probably the best English forward before his injury (ahead of Sturridge, Welbeck, Rooney etc.)
He's been out for an expected time for his injury (ACLs are always 6-9 months). And most players these days make full recoveries from them.
He'd be a £30m player if it wasn't for his short contract and injury, so £10-15m would be a bargain.
added to the fact he seems to be a player that the manager actually wants - for good or for bad (he is not garbage) we should bring him in
