Already people moaning it's "another Sancho".. let's get this right, Pep and the club showed faith by offering him a contract. Not loaning him out, not selling him with buy-back. A proper contract that was reward for his progression and with a view of bringing him on. When he refused, he was left out of the US tour as his commitment isn't reciprocated and we all know he went AWOL afterwards. His skill was never in question. His temperament is. He's flash, cocky, and very confident, which he's allowed to be and I know that side of the game grates a lot of people... but indiscipline isn't acceptable.
So now we turn to Diaz, another youngster that is above his peers at youth level, but looks like a fish out of water (at the moment). We've seen it many times before. Garcia, Lopez, Suarez.. the players quickly ship out and go on to make a decent career elsewhere. Personally I see the skill, but don't see exceptional talent with vision, movement etc. I see a great dribbler who's not strong enough.
