Concerning the red card that was given casimiro in Manchester United match against Southampton. I strongly advise the management of Manchester United to appeal that red card because it is not deserving. Most times I question the officiating ability of the English Premier League referees. Especially when they would refuse to make use of the VAR even when there is an obvious need to use the electronic device.
Meanwhile Manchester United need to find a way to start playing well, even without their talisman midfielder in the pitch. If not, they will keep dropping points.
The refrees are humans and sometime can make some wrong decision on giving players red card on a match, Which could throw the whole game in the favour of a particular.
Midfield players are just like the engine of a car, There are kinds of players that their presence mean so much for a team, and in reality it does affect the club and I think this was the case for Manchester united during their game with Southampton and why they didn't do well as expected in their game.
