Kevin De Bruyne insists that his apparent on-field argument with Manchester City team-mate David Silva on Tuesday night was 'just a little discussion'.
The City pair were seen squabbling as they left the field at half-time, after the Belgian had made a beeline to the fourth official.
De Bruyne was trying to complain to the official about the referee's decision to give Napoli a first-half penalty, which Ederson saved from Dries Mertens.
But BT Sport footage appears to show captain David Silva preventing his team-mate from venting his anger, which De Bruyne did not take too kindly to.
