I'm a huge fan of Lamela, he is quality, whilst anyone can hold an opinion, I do genuinely question the individual that thinks Lamela is shit, honestly, think you know fuck all about football, but that's just my opinion.
We do however have a problem with him, it has absolutely NOTHING to do with ability but everything to do with fitness. In the professional game, there is absolutely no point in having a player in the squad that is consistently unavailable to play. I love what our club has done with him (and that also proves to those who think his shit that Poch thinks his mustard and worth looking after), the club delayed his operation and choose to work on the problem (you can't undo an op, it's the last resort), when he clearly pushed for the op himself as his problems were still present, the club were still with him and offered him a new deal etc.
But if he can't contribute to the team there is no point having him in the team.
