I would welcome him back for 20m, not just 15.
If he ever comes back, he'll know that it'll probably be his last move and I don't think there'll be any miserable expressions.
He's still a top class striker and I can't imagine how mouth watering it'll be with suarez as strike partner.
I suspect the problem is not him but rather with chav's style of play. He's suited for our counter-attacking style and that's when he's move devastating.
How many times have we seen this season for suarez to break on an attack only to see no other red shirts in the box to inter-change play with him? Torres could be the answer.
That's more or less everything I was gonna say. I'd be happy enough for the club to buy him back for £20m, considering what he was sold for.
Don't know if any possible return would be for the best with regards to dressing room morale. I think there'd be a few players who wouldn't be too happy to see him back - especially if he was to come back with the same poor attitude.
