Former Juventus captain Alex del Piero says Carlo Ancelotti was clearly upset during Real Madrid's draw with Manchester City.
The first-leg of the Champions League semifinal finished 1-1 at the Santiago Bernabeu on Tuesday night.
Del Piero observed: "Ancelotti was very nervous, maybe it was because there was Orsato fourth official... He said all sorts of things to him, his bench got very angry, especially before the equaliser. It was a very, very heartfelt challenge.
"I'd say a fair 1-1, City deserved in the first half and Real was ahead, in the second in the opposite direction and they drew.
"Perfect balance, Manchester faded a bit as the minutes went by, Guardiola also got very agitated on the bench, he was angry with Gundogan and Stones. Two monstrous teams, incredibly strong."
