The Benitez hysteria in the press seems to be put around by "intermediaries close to Benitez" or "intermediaries close to Chelsea". It all sounds like bollocks to me. I really think that if there is a breakdown inside Chelsea (which seems likely) and if it causes AVB to go (which is very possible) that I think appointing Benitez would be the very worst thing. Benitez has a history of slagging of Chelsea players individually and calling them cheats. I doubt that's been forgotten by the players. It certainly hasn't been forgotten by this fan.
If Chelsea really do need a short-term manager with a history of club success and who has the respect of at least some of the leading players, I can't think of a more qualified available candidate than Capello. Can you?
