Speaking to the media, Guardiola said: "For Erling it's not easy. Arsenal is a physical team, in a good way, in many aspects.
"For 90 minutes, the central defender, Gabriel, pushed him, hacked him, hugged him and kissed him. The Premier League is that way.
"You have to stand up and defend your position. And now I am being asked to adjudicate on what Erling has done? I don't buy it.
"The end of the game was so emotional. In the end, a human being has to react."
