The UEFA Champions League returns on Wednesday with Matchday 8, which could very well be the most hectic, chaotic day in terms of results that the sport has ever seen. All 36 teams will be in action as 18 games will take place simultaneously at 3 p.

The first Champions League games to be played in January include one with shocking possible consequences in an unpredictable debut season for the 36-team format. Paris Saint-Germain vs. Manchester City on Wednesday is a clash of super-wealthy state-backed teams currently a barely believable 25th and 22nd in the standings.

Ahead of today's visit of Manchester City, Paris Saint-Germain know that a slip-up could cost them their place in the UCL.
