Roman Abramovich's time at Chelsea has shown he isn't always the most patient with a manager when the club goes through a bad patch.
As a result there's been plenty of speculation surrounding Jose Mourinho's future at Stamford Bridge, especially following last weekend's defeat at West Ham and the midweek League Cup exit at Stoke.
Several names have been put forward as potential replacements for Mourinho, but it appears that Abramovich is running out of options.
Following reports that
Carlo Ancelotti would be considered for a second stint at the club, another of the Blues' former managers also appears to be one of the candidates.

Fichajes reports that Andre Villas-Boas has made it onto Abramovich's shortlist.
This comes after Chelsea were understood to have shelled out £13.2m in compensation to release Villas-Boas from his Porto contract in 2011, the highest fee of its kind. He lasted less than a year before he was sacked.
Currently in charge at Zenit St Petersburg, Villas-Boas will leave Russia at the end of the season after rejecting the club's offer of a contract extension.
