Chelsea stats

We played PSG on the last occasion, in 2013/14 when Jose Mourinho was in charge, and we progressed to the semi-finals on away goals having drawn the tie 3-3 on aggregate.This is our 10th quarter-final in the competition. We have progressed in seven of the previous nine.Chelsea have reached the Champions League quarter-final without losing a game for only the second time. 2007/08 was the other when we went on to lose the final in Moscow.The loss at Bayern Munich last season is our only defeat in 15 European away matches (11 wins, three draws).Our record against Portuguese clubs is 10 wins, one draw and two defeats. Away from home we have won three, drawn one and lost two (both to Porto).Chelsea have won all three knockout games against Portuguese sides; Porto in 2006/07 and Benfica 2011/12 (both in the Champions League quarter-finals) and the Europa League final against Benfica in 2013.

Chelsea are looking to win five consecutive away games in the Champions League proper for the first time since a run of five between September 2003 and April 2004.We are unbeaten in this season’s Champions League.Only Man City (one) have conceded fewer goals in the Champions League this term than Chelsea (two), while only Pep Guardiola’s side (seven) have kept more clean sheets than the Blues (six).

Milestones

Porto stats

They have only lost to Real Madrid more times (six) in the Champions League than they have against Chelsea (five).A 95th-minute Toni Martinez goal secured all three points for Porto against seventh placed Santa Clara on Saturday. They remain second in the Primeira Liga, eight points behind leaders Sporting Lisbon. Porto are unbeaten in the league since 30 October. In the 34 games in all competitions since then they won 24 and lost three (two in the League Cup and Juventus in the Champions League).Pepe (38 years 40 days) is set to become the oldest outfield player to appear in a Champions League quarter-final since Ryan Giggs back in April 2014 (40 years 123 days v Bayern Munich).Malang Sarr could be the second Chelsea loan player to play against us in the Champions League following Thibaut Courtois for Atletico Madrid in the 2013/14 semi-final. His last appearance for Porto was in the last round of the Champions League at Juventus on 9 March.

Sergio Conceicao has never managed a team against Chelsea although he has played against us twice for Lazio in the Champions League in 1999 and 2003, winning one and losing one.
