There's been a zillion González players in Uruguay so probably someone got called Mágico at some point, but I don't have any recollection of the original one playing here. Probably didn't, or I would have noticed it.
I only got to watch him a few times as I wasn't really into Cádiz (nor was Uruguayan TV) so it was more the sort you heard about and got to see 2-3 times a year when playing the big teams, which naturally led to counterattacking setups. That suited him as he had a ridiculous turn of pace, and I mean ridiculous, more so than Robben and even Boniek. It was surprising really as he was a complete basketcase who didn't like training, didn't consider playing football a job, etc. A bit like our George.
I suspect he must have been inconsistent, at the very least, but couldn't swear by it. He was certainly laid back and that's where he was nothing like Robben or Boniek, he didn't really do this running up and down the pitch all game like a maniac, which in turn made it quite deceptive because defenders would just see this guy playing football normally, at normal pace when not standing still, with good passing and dribbling (the Mágico side)... And out of nowhere he would go all Speedy Gonzalez on you and created these major "WTF?" moments. It wasn't really the runaway situations (like Boniek's) when he sprinted and left his marker way behind, nope, he would just be quick enough to leave him behind and not a notch higher than that. You always knew he still had an extra gear if needed. The shockers were when he didn't start off the shoulder but 15-20 yards behind a defensive line and beat them to a ball placed 15-20 yards behind it. Mind, there must have been an element of the defenders themselves feeling safe and being a bit lackadaisical about it, but it was astonishing nevertheless. Best example I could find was over a longer distance, but it gives you the picture!
