Manchester City and Crystal Palace's coaches squared up to each on the sidelines during an action-packed FA Cup final at Wembley. The incident occurred just after the hour-mark, when Palace - already 1-0 up at the time - had seen Daniel Munoz's goal ruled out by VAR. The match had already been filled with several incidents - with Palace goalkeeper Dean Henderson escaping a red card and City's Omar Marmoush having missed a first-half penalty after Erling Haaland decided not to step up to take the spot-kick. However, the match was about to descend even further into chaos - with Palace coach Paddy McCarthy squaring up to City doctor Max Sala on the sidelines. It came after Palace had brought off former swansea -city-fc> Swansea City loanee Marc Guehi. The England international had been treated for a head injury minutes before, but had initially seemed fine to continue. However, as he was substituted, Sala appeared to take issue with his departure. And that lead to former Manchester City youth player McCarthy squaring up to the doctor. "Look at this, look at this," said BBC's Guy Mowbray on commentary. "Two of the fitness/medical coaches squaring up to each and being forced to part here. "Marc Guehi is being taken off so that's clearly the after-affect of some sort of concussion he was suffering with. "Maybe that was the reason for the furious row going on between the medical teams." Commenting on the disallowed goal and the touchline fracas, former England striker Alan Shearer added: "That was a crazy three or four minutes." Mowbray continued: "It's been that sort of day. "Maybe it wasn't the medical team, Paddy McCarthy was involved - the Palace coach. As the camera cut back to the sidelines, with things having subsided as the guilty parties sat back down, he added: "Now they've all calmed down there and are finding it a huge joke behind Pep Guardiola."
