Manchester United pulled off a brilliant comeback against Juventus last night.
Jose Mourinho's side were 1-0 down with 10 minutes to play and were staring at another Champions League defeat at the hands of the Italian side.
But, Juan Mata struck with seven minutes to play and a Juventus own-goal six minutes later gave United an unlikely victory.
While there was no shortage of drama on the pitch, the biggest controversy of the game came shortly after the final whistle.
Mourinho had been taunted by the Juventus fans throughout due to formerly being the manager of Inter Milan.
And, after his team had secured the win, he turned around to the Turin crowd and cupped his ears.
Mourinho later revealed his actions were down to Juventus fans insulting both his family and his Inter family during the game.
This brought about a mixed reaction from those in the footballing world.
While many defended Mourinho, one who expressed his opposition was Graeme Souness.
Souness, a former Liverpool player, is never shy in attacking anything to do with Man United.
He has criticised Paul Pogba on numerous occasions in the past few years and he didn't shy away in condemning Mourinho's actions.
Souness appeared on Virgin Sport Studio yesterday and when asked if Mourinho was entitled to act in such a way, Souness responded, per 101greatgoals.com: "No, 100% no. It could cause a riot.
"The Italians have just lost, he’s remonstrating with the supporters and the Juve players get involved with him. You can’t do that.
"We’ve both been managers, you get that anyway. That’s part of the deal. If your team is winning away from home, if your team’s not play, you get it. You’ve just got to take it on the chin."
Mick McCarthy was alongside Souness at the time and he couldn't help shutting down Souness perfectly.
In response to Souness' comments, he said: "I have to say, I don’t think you and I can sit here pontificating over Jose Mourinho when you’ve stuck the flag in the middle of the pitch in Turkey, and I’ve had an over-exuberant celebrations in front of the Norwich fans.
"We’re the last ones who can be doing that, to be honest."
That is quality. For context, McCarthy is referring to Souness' actions when he was Galatasaray manager in 1996.
After beating fierce rivals Fenerbahce in a domestic cup final, Souness stuck a giant Gala flag in the middle of Fenerbahce’s pitch.
It's no doubt those actions are a lot worse than what Mourinho did last night.
The exchange quickly went viral with many fans laughing at McCarthy's reply.
