Not sure about Man United in the first game against Munich. I'm not sure they can bring points. With this kind of situation, Man United looks weak. Some players were injured and got some cases. It looks like Man United is a goat who came to the Tiger stable. They need a miracle to get just one point. But to qualify in the knockout phase, Man United's chances are still very open.
The chance is pretty small for utd to win the game against bayern. Utd will be playing in allianz arena and ten hag's club will have faced kane's squad. I wonder how many goals will be conceded during the match. 
Bayern will not even miss an opportunity to get 4 points by playing at home. Manchester united at the risk now caused by the club potentially lose against bayern. It must be noted that if MU will be conceded a lot of goals if ten hag will be using meguire and evans as starting line up.
Those guys are terrible defenders. Ten hag needs to find another option to face bayern. Megurei was not as good as when he used to be.
BTTS is making sense for this match but im sure if bayern will be scoring first rather than united. I can't even imagine if antony will not come to play against bayern. It's a disaster for manchester united at this moment.
Utd faces another horrible situation when it must be playing against bayern in the first match of group qualifier.
