Cristiano Ronaldo out to end goal drought - Champions League in Opta numbers
Cristiano Ronaldo rarely goes five games without scoring but he heads into Juventus' clash with Manchester United seeking his first Champions League goal in six outings.
He is not the only one hoping to end an unwanted streak, as AEK Athens travel to Bayern Munich aiming for a first away victory in 24 matches in Europe's premier club competition.
With Roma playing away at CSKA Moscow and Real Madrid travelling to Viktoria Plzen, Wednesday's fixtures could deliver some surprises.
Our Opta-powered preview gives the lowdown on the key numbers for each contest.
Benfica v Ajax
5 - Ajax have not lost any of their last five competitive games against Benfica, picking up a draw and four wins including their 1-0 victory at Johan Cruijff Arena in October.
4 - Benfica have picked up just four points in their last 11 Champions League group matches, and have lost all of their last four home games in the competition.
Bayern Munich v AEK Athens
10 - The German champions relish matches against Greek opposition, having not lost in all 10 competitive encounters, scoring 18 without reply in their last five home matches against Super League sides.
23 - AEK are aiming to end a streak of 23 winless away matches in the European Cup/Champions League, leaving them over half way to matching Olympiacos' record sequence of 45 games between 1959 and 2006.

Lyon v Hoffenheim

Manchester City v Shakhtar Donetsk

24 - City managed 24 shots in their 3-0 win over Shakhtar last time out, which was the most the Ukrainian side had faced in a Champions League match since Real Madrid hit 26 against them in September 2015.
