Barcelona, Chelsea and Liverpool all feature in the best Opta facts ahead of Wednesday's batch of Champions League matches.
Luis Suárez is bidding to end a miserable run in away Champions League matches as Barcelona travel to play Slavia Prague in one of eight games on Wednesday.
Ajax v Chelsea
5 - If he scores against Chelsea, Quincy Promes will become the fifth Dutchman in the history of the European Cup/Champions League to score in three consecutive appearances for Ajax. The others are Johan Cruyff (April 1969), Ruud Geels (November 1977), Ruud Krol (October 1979) and Patrick Kluivert (October 1995).
8 - Since losing 3-0 at Barcelona in March 2018, Chelsea have lost none of their eight away European matches (W6 D2 L0), their longest ever unbeaten away run on the continent.
Genk v Liverpool
14 - Should Genk fail to defeat Liverpool, they will set a record for games played in the European Cup/Champions League without winning. They have played 14 so far (W0 D8 L6), level with Floriana and Shamrock Rovers.
1 – Liverpool have won only one of their last 10 away Champions League group-stage matches (W1 D3 L6), losing each of the last four in a row.
Inter v Borussia Dortmund
6 - Inter are winless in six European matches against German opposition (W0 D1 L5) since a 3-2 win over Bayern Munich in the Champions League in March 2011.
2 – Dortmund have only conceded two goals in their last eight Champions League group stage matches, keeping clean sheets in seven of those matches.
Slavia Prague v Barcelona
4 – This is the first meeting between the two sides in Europe, though Barcelona have won all four of their previous Champions League meetings against Czech opponents.
19 – Suárez scored twice against Inter on MD2 in Barcelona's 2-1 victory, but the Uruguay striker is goalless in his last 19 away Champions League matches, attempting 59 shots without success since scoring against Roma in September 2015.
