Pep Guardiola and Paul Cook were reluctant to discuss their touchline spat during Wigan’s victory over Manchester City on Monday.
The League One Latics caused one of the biggest shocks in modern FA Cup history by beating the runaway Premier League leaders thanks to Will Grigg’s second-half effort.
Home fans invaded the pitch at full-time to celebrate the victory, goading away supporters who managed to throw an advertising hoarding onto the pitch.
Sergio Aguero was also involved in an altercation with a fan, but tempers had flared even before half-time when Guardiola and Cook remonstrated on the touchline.
The two managers clashed after Fabian Delph was sent off.
“It’s a red card. It’s an unnecessary action,” Guardiola said. “The referee decides what he decides. It can be a red card.”
Asked about the touchline row, he said: “You want to ask me about football, ask me about football. Nothing happened in the tunnel, nothing happened with my colleague. It was just, ‘Stay in your position,’ that’s all.”
Cook had his say, adding: “I think we should speak about the game. We’d all have different opinions.
“There’s a lot made of tackles. I felt at the time it was a straight red. I don’t think Pep and his bench thought it was but that’s football. We’re never going to agree.”
