lol, barca are not the best attacking side in the world. How did they do in the league, frequently all their big names would dissappear. Henry is living off his reputation of how he played about 4 years ago now, his last season at arsenal was dire, the season before only semi good, the 2 since, woeful.
People live in history and its boring. Liverpools current side didn't win a cup back in the 60/70's, Barca were a massively worse side last year and not fantastic the year before. etc, etc.
Wes Brown was frequently found being left behind, anyone/everyone can have a few fantastic games and a few bad games, the worst striker in the world can and do score against the very best teams sometimes, thats football. Overall brown is average, very good on his best day but mostly fairly clumsy and makes plenty of mistakes.
Caragher was possibly best in league but that was almost 4 years ago now, last 2 years he's been a joke, this year, awful. Rio ferdinand only looks so good because Vidic has been world class and moping up his mistakes, Vidic only looks quite so solid as you see him have to mop up Rio's mistakes and he plays the furthest back defender role whose job it is, is to mop up mistakes. By being the "stepping out" centre back you will make more mistakes than the other type of centre back. No ones directly comparable really.
Vidic/Rio is just as strong as Terry/Gallas was. Rio + anyone else in the man U squad or any english setup is no where near as strong. Likewise Terry has never looked as good as he did alongside Gallas. You simply can not distinguish a single centreback out as being great, you can only defend effectively as a pair. left/right backs are a little more singular and more comparable to other left/right backs. Cole was great, not anymore. Neville is probably englands best player, he's been out injured, but thats not the same as playing badly for a year as say in Carraghers case. Theres nothing to suggest he'll come back and be less reliable than he was for the decade before he was injured where he really never changed in reliability.
