I read the headlines and was surprised to see the replay of the red card afterwards. There's no intention to harm but he went studs first on the calf and then all the way down to the foot. Red card is harsh but imho not a blatant error. You can't go studs first.
There's a pattern of referees giving unreasonable red cards to Arsenal, and those same referees getting lavish trips to the Dubai, which is where the owners of our title race rivals for 2 previous seasons are located.
It's a similar conflict of interest, if not outright corruption as Justice Clarence Thomas getting free all expenses paid fishing trips and other goodies from a billionaire who wants to influence Supreme Court decisions.
