@nickwebb2017 With regard to the earlier concussion substitution, Marnus Labushagne was the first ever concussion substitute in test match cricket. He replaced Steve Smith after he was struck on the head by Jofra Archer during the second ashes test at lords in 2019.
Apparently Jose Mourinho has just been seen leaving Old Trafford driving very fast.
He's off to find the nearest speed camera in an attempt to get 3 points this Christmas.
