Ireland manager Martin O'Neill couldn't resist the temptation to give his former player Robbie Savage a verbal jab live on TV, in a moment that had his fellow BBC pundit Alan Shearer in stitches.
'Neill was a panelist as his former club Leicester took on Derby in an FA Cup fourth round replay, with the BBC experimenting with a camera in the Derby dressing room as their manager Steve McClaren delivered his half-time team talk.
That inspired O'Neill to suggest he would not want such a public display of his interval analysis, which inspired Savage to suggest he never looked forward to the Irishman coming into the Leicester dressing room at half-time during his time working under him.
"To be fair, there were times when I was playing at Leicester that I didn't want you in the dressing room either as all you did was have a go at me," suggested Savage.
O'Neill responded with a moment of typically sharp whit as he suggested: "There was a very good reason for that."
You can see his explanation for that comment in the video below:
O'Neill was also pretty unforgiving as he suggested BBC co-commentator Graeme Le Saux 'needed to get out more' after he claimed to have enjoyed the woeful first half of a game that eventually sprang to life as Leicester secured a 3-1 extra time win over Derby.
