Messi had a £35mill release clause on mine aswell, but he wouldnt come to me 'cos im boro & only finished 6th in the league. I got Aguero for the same reason & Pato for £29mill.
The most ive paid is £50mill to Liverpool for a Scottish RB regen called David Morgan. I just turned down £40mill from Real Madrid for my regen CB called Zabalza.
The highest fee on my game was £62mill for Bojan by Real Madrid. They bought him off Benfica who got him on a free when Barca released him for some reason lol!! He wouldnt come to me either.
