Andy's question is a fair one, and its something I've thought about in the past. Torres isn't a flair player in the truest sense of the word, althought here is much balletic beauty at times in the way he glides accross the turf. He has a trick but isn't tricky, has skill but isn't overtly skillful and has flair but isn't a flair player. Equally, Gerrard has flair in his ability to quicken the play in the snap of a finger, in his shooting and in the perception of his passing. Not really a flair player though in the sense that most people think of.
I guess what most mean when they say flair player is one who can be excused some of the water carrying for the team. Perhaps one who doesn't put the full shift in all the time, in the hope that more often than not they will provide a spark of gamebreaking quality. All well and good of course if more often than not they do, and although they may shirk some of their ball winning duties they don't forget they still have to protect the ball for the team, make it stick and occasionally take a knock or two for the greater good. Flair players who continuously lose possession, go missing for long periods and generate resentment within the group are no good to anybody. Ronaldo at man Utd would be one that Darren Fletcher would no doubt have no complaints about doing the water carrying for, whereas cisse by contrast would likely get his head kicked in were it not for the fact he was/is such a nice fella.
