It happened during the game. It was a bit of fun from the fans and Pep but it was being made out to be more than that afterwards
Slot on Mo saying he's played his last home game against Man City... "Maybe knows more about the 115 charge, so expects them not to be there next season"
I just watched a short of Salah doing keepy ups while he was waiting to take the penalty and saw something I'd previously missed, Haaland whispering in the keeper's ear. I wonder if that was what the joking between him and Salah was at the end. Salah asking him what he'd said to the keeper. I remember after a game, maybe two seasons ago, when Salah went to the opposition keeper straight after the game (Ben Foster?) and asked him which way he would have gone had he been given the penalty. He really takes this stuff seriously..
