Squad sheets: Chelsea v Sunderland

This fixture suddenly looms large and awkward for the hosts. Chelsea's home form has been too jittery for comfort, their propensity to implode when chasing victory having cost them three times already. The fragile Sunderland of early season might have offered some respite, but Martin O'Neill's revitalised charges represent a considerable threat. "He's had the right kind of impact there," said André Villas-Boas of his opposite number. "The team were low in motivation and self-belief, but they are now inspired." Steve Bruce's side won 3-0 here last season. In that respect, O'Neill has a hard act to follow.
