I know and Fernandes a few weeks back, feet off the ground is dangerous play whether intent or not so red card but they got away with one a few weeks ago, so evens it up. I hope the lad is ok which is the important thing.
Not only a red, i think they should retrospectively ban him for the last few games and mark them down as losses instead.
His foot may well be over ball but it's not even towards the Saints player. He came in from the side and Casemiro's foot literally bounced off the ball and onto the incoming player. If he'd gone in above ground height at the opponent, fair enough He didn't.
