What, John Terry is at least equal to Carvalho, neither of them make mistakes, and Terry certainly doesn't look out of place next to him. Do you even watch Chelsea matches when they are on TV? I would say if anything Terry would get more recognition because he does the more memorable things like block shots and he also wins more headers. The pair of them are quality and I honestly wouldn't swap either of them for any defender in the world.
As for the Arsenal defensive shambles point, Toure and Cygan are the ones to blame, and obviously Lehmann, if Campbell is so bad then why did Barcelona want him when his contract with the yids expired. United have good keepers which is why they let in less, and the last world cup was two and a half years ago, wait till the next one and if Terry plays he will finally be able to get you to shut up.
One last thing, I am aware that Ferdinand didn't play from January, but
http://www.sporting-heroes.net/footb.../2003-04.htm#1 Arsenal let in the joint second least amount of goals at home, look who is in first place, thats right, Carvalho might be great, but he wasn't their last season, thats largely down to Terry and Carlo that we had the best home record in the league last season, and look who had the two best away record, I would say Arsenals great defensive record was much more to do with Campbell then anyone else, the guy is solid, and prevents alot of goals.
