The Roman Abramovich era at Chelsea is coming to an end after the multi-billionaire announced he intends to sell the club.

Having the purchased the club in 2003, Abramovich oversaw a west London revolution as Chelsea soared from perennial bridesmaids to European royalty.

He ploughed money into the club, giving his many managers all the support they needed when it came to the acquisition of new playing talent.

He was an ever present at Stamford Bridge as well, regularly watching his team from the terraces of the famous stadium.

Silverware flowed through doors, as did managers, with Abramovich always making quick and decisive decisions with regards to the men in charge of the side.

While they may not have gone down well among the purists, the methodology certainly paid off, with the Blues regularly claiming the biggest prizes in the game.

There were certainly some heady days and some that are perhaps better forgotten.

Some signings changed the face of the club, others folded under the pressure. Some managers built dynasties, others lasted just a few months before being shown the door.

So, as the sun comes down on Abramovich's time as the Chelsea owner, we thought we would see just how well you remember his 19 years at the helm.

You have 20 questions to prove you're true Chelsea egg-head. Good luck!
