Wednesday's Champions League action includes high-quality matches such as Tottenham versus Inter and Paris Saint-Germain against Liverpool, as clubs seek a place in the next round.
PSG's Gianluigi Buffon could become the third goalkeeper to record a 50th clean sheet in the competition, with the Ligue 1 giants hosting last season's beaten finalists in a crunch clash in the French capital.
Monaco boss Thierry Henry will seek his first Champions League win as a head coach at the Wanda Metropolitano, while an injury-hit Barcelona are in action at PSV.
Here, we take a look at the key Opta numbers behind each of the eight matches on Wednesday in Europe's top competition.
Atletico Madrid v Monaco
18 - Monaco have not kept a clean sheet in their last 18 Champions League games, the longest run of this kind by any French club in the competition.
16 - In contrast, Atletico have only lost one of their last 16 home games in the Champions League, winning three in a row. That defeat came last September, 2-1 against Chelsea.
