Chelsea have kicked off the Champions League knockout stage tonight with a delicate clash against La Liga leaders Atletico Madrid.
The Blues dominated Group E ahead of Sevilla before Christmas and have impressed since Thomas Tuchel took control.
But the German will now face his biggest test to date when he takes his Chelsea side against Atletico.
The Spaniard was a finalist for Bayern Munich in Group A but is ahead of his league.
They have only won just one of their last four which could give Chelsea confidence again but facing Diego Simeone’s men is also difficult.
The latter two 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: team news
Atletico Madrid boss Diego Simeone has praised Chelsea manager Thomas Tuchel ahead of the meeting.
“We just have to have a good game against a very great team, with a new coach, a very great coach and an important coach who has done his job wherever he’s gone,” said Simeone.
“Chelsea are a very strong club, they are developing every time and every year. They bring in a lot of new players and invest in young players.
“When they didn’t see the investment and it didn’t pay off, they had this change. They brought Tuchel but it’s a very big team and since he came he has changed the numbers a lot.
“You just have to look at what the players have at the goalkeeper, the striker and anyone on the bench can play very well in any team in Europe.”
