He is a very high risk/high reward GK. In those two matches we played against them in the CL he made tons of mistakes. The biggest one was the Morata goal in Munich that was wrongfully called offside.
It could have been Neuer went right after him and didn't obviously make a attempt for the ball or anything he just got in his way and shoved him. I think it should have been a penalty. Neuer making major errors as usual and getting a free pass as usual
