Jose Mourinho told Sky Sports” A team from the lower division
Ion won. A big day for them”
1988-89 was the last time the Robins reached the semi-finals of the competition; it was a deserved victory against United; they went ahead with Joe Bryan’s absolute lightning bolt of a shot into the top right corner beating United keeper Sergio Romero.
United captain for the night Zlatan Ibrahimovic scored a deflected free kick to bring the champions back into the game. Getting his first start since April.
But Korey Smith finished the game off in the games dying minutes with a coolly taken strike into the bottom right corner of the goal, causing a joyous scene as United became the 4 premier league team to be beaten by the Robins this year.
Mourinho spoke after saying” they were a bit lucky but they fought a lot to be lucky. Everyone was waiting for our goal so they were lucky. We hit the post twice. But they played brilliantly, they fought like it was the game of their lives which probably it was. A beautiful day for football."
United will not be retaining their title this year
United had changed almost their whole starting line-up after their 2-1 victory over the baggies on Sunday, but a team still including Anthony martial, Marcus Rashford, Paul Pogba and Zlatan.
The United manager had implied that some players in the 11 had ceased upon their chance to impress, saying "The reality is that the players that were on the pitch were the ones that were not in the last match. They are the ones that are not going to be in the next match. I think they lost a good opportunity also to play semi-finals and also to have two more matches to play.
"But I don't want to blame the players at all because I think they were professional - it wasn't a case of 'we don't care about the game' or 'we don't have responsibility' or 'we don't have pride’. “I think they showed they had that after the 1-0 [the first goal] and they had that until they scored the second goal in the last few seconds and we had no chance to react."
Johnson, who is having his best season so far, hoped him and Mourinho would share a bottle of wine after the game, which had cost the Bristol boss £450 to order especially from Portugal.
But he will enjoy the taste of success more for the Championship club, who have now beaten four Premier League sides in the competition already so far this season will Manchester City be added to that list, as they’ve shocked the nation once again.
