Andre Villas-Boas was sacked as Chelsea manager on Sunday as Blues owner Roman Abramovich wielded the axe for the sixth time since buying the Premier League club in 2003.

Andre Villas-Boas has been sacked by Chelsea after less than a season in charge at Stamford Bridge, the Premier League club announced in a statement on their website on Sunday.

Villas-Boas, who arrived from Porto in June 2011, has paid the price for a dismal run of results that left Chelsea in fifth place and on the verge of elimination from this season's Champions League after a 3-1 defeat at Napoli in the last 16 first leg.

Looking back at Abramovich's history, it's quite clear that he has very little patience with his managers. Here's proof. All the stats you'll need to know about Roman's affairs with Chelsea managers since he took over the club in 2003.
