Neil Warnock labelled Wolves coach Nuno Espirito Santo a "total disgrace" a few moments after yelling expletives in the Portuguese's direction following a charged end to Cardiff City's 1-0 defeat.
Wolves left Wales with a slender win after Cardiff failed to capitalise on winning two late penalties after Ruben Neves had broken the deadlock with a fine free-kick in the 67th minute.
Gary Madine saw their first spot-kick saved by John Ruddy in the second minute of stoppage time and Junior Hoilett then put his penalty effort onto the crossbar a few moments later, sparking wild celebrations amongst the Wolves coaching staff, which did not go down well with Warnock.
