Jose Mourinho's star-studded Manchester United side were knocked out the Carabao Cup on Wednesday night, losing 2-1 to Bristol City at Ashton Gate.
Korey Smith scored a 93rd minute winner for the hosts to spark a pitch invasion after Zlatan Ibrahimovic had levelled for the holders with an excellent free-kick.
The Championship side were drawn against Premier League leaders Manchester City in the two-legged semi-final.
Bristol City manager Lee Johnson described it as a "brilliant draw" and claimed his players would not be celebrating the shock win over United.
"I thank Jose Mourinho for his words before hand, and for the game," said Johnson. "You don't want to see a pitch invasion but you have to understand the passion.
"I will not let them celebrate tonight, we have got a big game on Saturday."
Mourinho's embarrassing post-match antics
Journalists were not happy with Mourinho regarding his post-match behaviour.
The Portuguese former Chelsea coach repeatedly described Bristol City as "lucky" in his post-match interview - but members of the media were left appalled by his antics immediately after the game.
According to the Bristol Post's Gregor MacGregor and the BBC's Shamoon Hafez, Mourinho "shot through" his press duties before the journalists could arrive and was therefore questioned by just one "local radio guy".
The post-match press conference lasted just two minutes and can be watched in full below.
"I think they were lucky," said Mourinho to the single reporter.
"Before the 1-0, we hit the post twice. At 1-1, we had all the dominance pf the game and we had the best chances. And then they scored the goal in a moment when he had no chance to fight back.
"They were lucky - but they fought really hard. They are a very good team and instead of being critical of my players I prefer to praise Bristol City."
Mourinho will be urging his Man United side to bounce back when they face Leicester City in the Premier League on Sunday.
They lie 11 points behind Pep Guardiola's Manchester City but have not yet given up hope of catching their local rivals.
