Im only repeating what has already been said but my days, that ball to Janmaat was unbelievable. So refreshing for both goals to see him pick the ball up and be positive and look forward and to initiate things.
In my view Mbemba was trying to get more leverage by using his arms to jump, as you do, and his arm stayed up. His head then turned in the direction of Fellaini then next minute the ball hits him on the hand.
Never a penalty in a million years!
