Chelsea kick-off their Champions League knockout stage tonight with a tricky clash against La Liga leaders Atletico Madrid.
The Blues topped Group E ahead of Sevilla before Christmas and have impressed since Thomas Tuchel took charge.

But the German will now face his biggest test to date when he pits his Chelsea side against Atletico.
The Spaniard were runners-up to Bayern Munich in Group A but are top of their league.
They have only won one of their last four which could give Chelsea confidence but facing Diego Simeone’s men is also difficult.
These two last met in the group stage of the 2017/18 Champions League campaign. Chelsea won 2-1 in Spain before a 1-1 draw at Stamford Bridge.

Atletico Madrid v Chelsea: What has been said?
Atletico Madrid boss Diego Simeone has heaped praise on Chelsea manager Thomas Tuchel ahead of the tie.
“We just have to make a good game against a very big team, with a new coach, a very big coach and an important one that did his job everywhere he went to,” Simeone said.
“Chelsea is a very strong club, they develop every time and every year. They bring a lot of new players and invest in young players.
“When they didn’t see the investment and it didn’t pay, they had that change. They brought Tuchel but it is a really big team and since he came he put a good change in the numbers.
“Just look at what players they have at goalkeeper, at striker and everyone who is on the bench can very well play in any team in Europe.”
