The Red Devils chief has spoken out on the threat of the Londoners just days after his coach Rene Meulensteen dismissed their chances by suggesting that the Blues' ageing squad would go against them this season.
Ferguson disagrees as he feels the quality and experience of the Chelsea side will see them a lot closer than the nine points' difference at the end of last term when United wrapped up a record 19th league title.
"They have tremendous experience with the likes of Frank Lampard, Didier Drogba, Petr Cech, John Terry, Alex, Nicolas Anelka, Fernando Torres - there aren't any young kids in that team," Ferguson told Inside United ahead of their September 18 showdown with Chelsea.
He added: "But they don't have 36-or 37-year-olds like Ryan Giggs. Lampard and Drogba are 33, Anelka is 32 - not dissimilar to [Michael] Carrick and Rio Ferdinand, and we wouldn't be saying they are dead and buried, would we? So why should they be? They'll still be a big threat and we expect them to challenge."
