I don't think so, it's just because he's annoying. Watching that game with no preconceptions, he was just very frustrating. The fact that he was occasionally brilliant doesn't make it less annoying, if anything it's the opposite. When you feck up a penalty at 1-0 with a silly run up that tends to stay long in the memory, particularly after spending the first half fannying about plenty (like trying nutmegs in your own half instead of just playing the simple ball) while doing very little. I think he's the only player in our team that plays with arrogance (he seems humble off the pitch though) and yeah, some of the time he backs it up...but then quite often he doesn't. Valencia on the other hand just does his job in such an unfussy way that even if he does have a poor game, you can't fault how he's gone about it. He has poor games just like Nani but never because he's been lackadaisical or careless, he's just been off form.
And it's also because he is more talented than almost everyone else in our squad that it is annoying that he doesn't show it as often as people hope/want/expect. He's quite possibly the most technically gifted player in our team, capable of defence splitting-passes, wonderful goals and sublime control...does that really all translate into end product as often as it should? I expect Nani to be a much better player than Valencia because he's much more gifted but I don't see that. He's a matchwinner though, someone who can create something out of nothing and just a wonderful technician, so he's worth putting up with. At times it looked like Nani was the only one on the same wavelength as Kagawa which just makes it all the more baffling and annoying when he makes such stupid decisions.
