Cooper had every right to comment but it was highly unusual for him to do so, And insensitive. Out of character for someone who was an assured communicator and player motivatorI appreciate the point you're making but I believe Steve had every right to comment on the feeble attempt to prevent Luton's equaliser, although I don't recall him mentioning Joe personally?
The game was Worrall's chance to get back into the team and make amends with Cooper. Following stories about friction in their relationship.
Then we had the triple substitution to defend a two goal lead - game management? Complacency? But with hindsight a mistake.
Cooper saying we should be more physical for the goal was clearly pointing at Worrall. Basically saying the thing you were brought on to do, the thing you are best at , you didn't do. The chance for reconcilliation lost.
Neither Cooper or Worrall come out of this well. Nor the fans who didn't welcome Worrall's arrival on to the pitch with the respect a local club captain would usually merit.
A complete mess.
