dos santos sucked at barca, spurs, ipswich town and galatasaray what does that tell you?
He went away from Barça at 18/19 years old, and scored a hattrick in host last game on his way out, with the little apperances he had there it cannot be said that he sucked there, at Spurs he did failed, but both at Ipawich and Galatasaray he thrived in, he was magical in the latter. And of course in Racing, Mallorca and now Villarreal he has been bossing, in a Villarreal squad that has the likes of Cani and Bruno Soriano, they are fighting for a european spot.
Either way, if we would bring a mexican player I would prefer Vela by far, he has been class for 3 years, and this season he had 3 motm performances in the last month's games against Barcelona.
