It's funny how few top class wingers there seem to be about at the moment isn't it? I mean, most of the teams here have either narrow formations, or Gerrard and Ronaldinho on the sides, purely because they're quality players who happen to be able to play there, rather than players who have excelled in that position*. The only other names mentioned for the wings have been Ribery and (not fat) Ronaldo, who, while good, aren't a patch on the likes of Pires/Giggs or the likes (names escape me at this point) in their primes, just a few years ago. That, and I guess there's a real over-abundance of quality central midfielders at the moment too, with Gerrard/Lampard/Makalele/Gattuso/Fabregas/Mascherano/Hargreaves/Ballack/Kaka and the rest.
Also, to add to the Gerrard debate, I honestly think Hargreaves is a better DM than him. Gerrard is definitely the better all-round footballer, but Hargreaves is a better tackler, and having played the holding role for most of his career, is more used to it, and can read the game better because of it. Gerrard, like Lampard, has spent too long playing alongside a straight holding midfielder these days, and have become slightly "lazy" as a result. They know they can bomb forward a bit, or ignore the oppositions movement, because Maka/Essien/Hamann/Sissoko will take care of the legwork for them. That's not to say Gerrard isn't a decent DM, he's just not as good at it as someone who specialises in it.
Same with Vieira really. He started out more as a holding mid, but he's definitely not these days. That's why he had Gilberto alongside him at Arsenal, and Emerson with him at Juve.
*Not that they wouldn't neccesarily be good there mind, just making a point.
