The defender said "heads dipped" after a host of missed chances against Young Boys before Marouane Fellaini snatched a late victor to send United into the round of 16 of the Champions League on Tuesday.
In the end, Marouane Fellaini's injury time victor allowed the Portuguese to vent on the sideline, hurling a drinks holder into the Old Trafford turf as United took the lead.
Nevertheless, Lukaku has become a trusted Mourinho lieutenant at Old Trafford, having played over 50 games in all competitions last season, scoring 27 goals.
"I kind of enjoyed it", he said, ahead of United's Champions League clash with Young Boys on Tuesday.

De Gea (below) has won only four major trophies since signing from Atletico Madrid for £18.9m in 2011, joining a club that had reached the Champions League final three times in four years. As he turned, he appeared to control the ball partly with his hand, before hitting a shot through Loris Benito's legs and into the bottom corner.
"From my position, David's save - only one save in the whole game - but it looks a phenomenal save", said Mourinho. We didn't play to be in trouble until the last minute.
"My players were very exhausted at the end".
"I was frustrated we couldn't score".
Arsenal must improve 'everything' for top-four Premier League finish - Unai Emery
Asked if his squad are playing as well as the teams in front of them, Emery said: "Sometimes yes, sometimes no". The Gunners are also unbeaten in sixteen games now.
"I'm pretty sure a proper manager would never criticise another one for emotional reactions on the touchline because it's déjà vu for them".
"Is about us as a team, is very hard for us to score goals".
"Without David [de Gea's] save, no winning goal", said Mourinho, in reference to his goalkeeper's goal line stop from Ulisses Garcia.
Mourinho has made six changes to the team which started the 0-0 draw against Crystal Palace, with Pogba's omission in favour of Fred the most high profile adjustment. "Tonight, you had Marcus Rashford playing as a nine - that's what you want, that's what you ask for all the time and you had". But with United struggling to compete in the Premier League and so much uncertainty over Mourinho's future, De Gea is prepared to bide his time and see what develops.
