Chelsea stats

We have gone out in the round of 16 stage in our last four attempts, to PSG twice, Barcelona and Bayern Munich.

Chelsea have never been eliminated in a two-legged European knockout tie after winning the first leg away from home (progressed from all 13).

Chelsea are unbeaten in four Champions League games against Spanish teams (two wins, two draws), keeping a clean sheet in each of the last three.

We are without a win in our past five games against Spanish clubs at Stamford Bridge (three draws, two defeats), since a 1-0 victory against Barcelona in the 2011/12 Champions League semi-final first leg.

Chelsea have played 12 two-legged knockout ties against Spanish clubs (four wins, eight defeats), most recently in the 2017/18 Champions League round of 16 when we went out to Barcelona 4-1 on aggregate.

Thomas Tuchel can now boast the joint-longest unbeaten run to start a managerial reign at Chelsea, along with Luiz Felipe Scolari (12 games).

We are one of three sides unbeaten in the Champions League this term, with Man City and Bayern Munich.

Since the beginning of 2018, we have won three and lost three penalty shoot-outs. We lost our one this season 5-4 away at Tottenham in the Carabao Cup.

Olivier Giroud is averaging a goal every 38 minutes in the Champions League this season, the best ratio in a season of any player to play at least 200 minutes that season in the competition’s history. It’s the best in a European Cup season since Ton Blanker in 1979/80, who netted one goal every 34 minutes for Ajax.

Giroud is now our third-highest European scorer.

Atletico Madrid have lost three Champions League matches against Chelsea, their joint-most against an opponent along with Bayern Munich and Real Madrid.

Atletico Madrid are unbeaten since our first leg meeting three weeks ago. They have won two and drawn two in La Liga and remain top, four points clear of Barcelona in second. At the weekend Atleti drew 0-0 at Getafe who had a man sent off in the 70th minute.

The Madrid side are unbeaten in their last five visits to England.

Atletico have lost all seven UEFA competition ties in which they were beaten in the home first leg.

Discipline

Mason Mount and Jorginho are suspended for reaching three yellow cards in the competition. Mount’s booking in the first leg after 55 seconds was the quickest card shown in the Champions League this season.

Mateo Kovacic, Hakim Ziyech and Atletico’s Renan Lodi, Marcos Llorente and Stefan Savic are a booking away from a one-match suspension in the competition.

Three accumulated cautions or a red card mean suspension for the next UEFA game, though all yellow cards expire at the end of the quarter-final ties.

Chelsea: Jorginho 3, Mount 3, Kovacic 2, Ziyech 2, Azpilicueta 1, Chilwell 1, Kante 1, Pulisic 1.
