Pep Guardiola was not involved in the post-game spat, but claims to know what went on and why. He told reporters afterwards: “I know what happened but I won't say anything. They [Arsenal] know it.” Gary Neville, who was on punditry duty for Sky Sports, said of the incident: “Football players don’t like set-pieces on the training pitch, let alone the opposition set-piece coach having a go.”
