London - Out-of-sorts Chelsea have a golden opportunity to restore battered self-confidence when they face Maccabi Tel Aviv in their opening Champions League Group G match on Wednesday.
The Premier League champions slumped to their fourth defeat in six games when they lost 3-1 at Everton on Saturday.

Earlier, Mourinho admitted the poor run of results were the worst of his career but added he was the man to lead Chelsea out of their hole.
