Bayern Munich coach Vincent Kompany said he doesn't fully understand how the new Champions League format worked after his team earned a hard-fought 1-0 victory over Paris Saint-Germain on Tuesday to improve their chances of reaching the knockout stage.

Paris Saint-Germain are at increasing risk of missing out on the Champions League knockout stages after losing with ten men away to Bayern Munich. It was a night for forget for Ousmane Dembele who was sent off for two yellow cards and also extended his record of most shots in the Champions League this season without scoring.

Bayern Munich host Paris Saint-Germain in a UEFA Champions League blockbuster this Tuesday at Allianz Arena. Both sides need to win with the Germans in 17th on six points and the French 25th with only four points from as many games.
