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.
I'm not sure either. But the opportunity still exists for Manchester United. 
That's what Man United is experiencing now, they are thinking about several players who have stumbled into cases even though they are an important part of their team, there are several players who are not yet fit but it looks like they will force this to achieve their victory even though it will be very difficult to beat Bayern Munich at the Allianz Arena .
Estimates are that Man United can only be runners up.
Of course I will enjoy playing for this group stage next week.
