Sometimes it is needed though. Leon walked a goal in for Bury when Doncaster scored by accident attempting to return the ball after Bury had put it out.
I remember Robbie Fowler once jumping up and protesting a yellow card for a dive that the referee was actually awarding as a penalty in his favour. He didn’t think it was a penalty and said so. He told David Seaman which way he was going to put it and the penalty was saved (why he didn’t just put it wide I don’t know).
Maybe there aren’t that many examples, certainly not enough examples, but players and managers should be encouraged to play fairly, and congratulated when they show sporting behaviour. I hate Leeds and thought Klich, Bamford and Jansson were disgraceful in their behaviour against Villa, but I have to applaud Bielsa for his actions and taking fair play into his own hands.
Smith’s players knew it was in and would have told him so in the dressing room at half time. The only way of correcting the error at that point was for Smith to instruct his players to allow us to walk a goal in. There is no way to put a rule in for that.
