Mata's probably more devastating in the final third than any Spanish midfielder, than includes Iniesta and Xavi, his record speaks for itself. Give it to him outside the opposition penalty area and he WILL punish you. He should be in there well ahead of Pedro, Cazorla and Silva, in fact, Valencia looked a better side when Mata was the playmaker after Silva left.
To be honest though, Spain have been so successful recently and have built that success on the foundations of the Barcelona squad, they could put Joey Barton in there and still dominate matches. The future of that team is ridiculous, Mata, Thiago, Isco, Muniain, Fabregas is still only 25 too. I'm gutted, the only half decent midfielder we're producing is Jack Wilshere, and I would say Josh McEachran is we hadn't stunted his growth for two years. Time will tell with him though.
