No one even thought about Bristol City's chances of eliminating Manchester United until the Red Devils put up a baffling display at Ashton Gate, giving the hosts the chance to stage one of their most epic wins...and one of Manchester United's darkest pages in history.
Joe Bryan and Korey Smiths scored Bristol's goals, which were enough to cast a shadow over the Premier League titans. Not even Zlatan Ibrahimovic's first goal of the season was enough to help Mou's men in their attempts to avoid embarrassment.
Bristol City will join Chelsea, Manchester City and Arsenal in the tournament's semis, while Jose Mourinho and his men are running out of options to finish this season with a trophy in their hands.
Here's how fans and experts reacted to Manchester United's loss against Bristol City.
Imagine losing to Bristol City after spending £300M. Only Jose Mourinho can do that.

2 - @bcfctweets are only the second lower league side Jose Mourinho has lost to as a manager in England, after Bradford in the 2014-15 FA Cup with Chelsea. Slain.

I've decided the time has come. For me it's Jose Mourinho out. The mindset and mentality of the players, tactics, strategy and their execution doesn't fit with the playing style or history of Manchester United Football Club. It's #JoseOut time for me. #MUFC

Textbook.
Bristol City have deserved this. Manchester United simply awful. Why on earth was Sergio Romero wasting time at 1-1? Just mistake after mistake. Woeful.
