Unsuitable to celebrate or simply show passion?
Jose Mourinho returned to his ear with his hands and adored Juventus fans after the dramatic return of Manchester United in the Champions League group in Turin on Wednesday.
Leonardo Bonucci returned to Mourinho to complain in the afternoon, while the attacker Paulo Dybala also asked him.
The unified boss then sank the official and his coaching staff in the tunnel.
Mourinho then said he had "respect for Juventus" and responded to the "insults" of domestic fans.
"In a beautiful Italian city I was injured 90 minutes," said Mourinho, who led Juventus rivals Inter Milan between 2008 and 2010. "I did not regret them. I just did a little bit.
"I know that millions of Inter's fans are happy with this. But I respect Juventus, their players, the manager, the quality they have."
Juventus coach Massimiliano Allegra was not too fazier and said: "Everyone has his own personal reaction".
"I can not say whether it's true or wrong," he added.
"You need to win with a little class"
There are mixed reactions with experts on BBC Radio 5 live and BT Sport.
Former Manchester United midfielder Paul Scholes said that Mourinho could show "a little class", while former striker Dion Dublin said that all attention had "turned to Mr. Mourinho".
Scholes talks about BT Sport: "That's where it goes. Sometimes you have to win with a little class and shake hands with the manager. I do not think it's necessary, but it's so."
Dublin on Radio 5 live: "Jose Mourinho was not really needed to be there. Everyone is happy to congratulate and some have gone to congratulate Cristiano Ronaldo.
"Then all the attention turns to Mr. Mourinho, he has his right hand in his right ear, as if to say to all Juve fans:" What do you got about it? "
The Portuguese got some support from Owen Hargreaves. The former Manchester United midfielder said that the club was "a big week" and the celebration was understandable.
Hargreaves at BT Sport: "This is not necessary, but this is an exceptional result, and for United and Mourinho is a big week."
