Definitely a foul by Mane and the correct decision not to give a penalty.
In general, players get away with planting a leg in the way of an oncoming opponent and buying a foul - which bothers me at times when it’s obvious the ‘shielding’ player has no control over, or intention of playing, the ball. It tends to be an accepted situation in the game though. However in this case, Mane is laughably far from the ball and, most damningly, is on the far side of this coming together in relation to the ball. He has prematurely planted his leg in the path of a player who is ahead of him, and any foul can only rightfully be awarded to Fellaini.
The attempt from Mane seemed borne of desperation, as do the groans from Liverpool fans. The consensus on MOTD was alarming. Neville brushed the claim aside in commentary during the game and I expected it to be forgotten about. Especially when they had another two, more legitimate claims in the second half. The Valencia handball I’m torn on - natural position and ball played hand, yet a good distance away and stopping a dangerous cross. Young grabbing Salah was the obvious one for me and that wasn’t even mentioned by Lineker and co.?
