I think the only thing against Messi is not his ability or value as a statement it is the actual cost. Barca seem to believe they have a strong case for getting a fee, if he costs £200m +300m wages, then no I don't want us spending 500m on him
Do they? I tried to inform myself about the likelihood of Messi's party being right and every source I found sounded like they seem to be. La Liga and UEFA apparently are on Messi's side.
