Manchester City and Liverpool both secured big away wins to put their respective ties to bed with 90 minutes still to play, yet United approached a trip to the Ramon Sanchez Pizjuan with a more safety-first style and secured just a 0-0 draw.
Mourinho confirmed that the Frenchman is now back in action, but having missed Saturday's 2-1 win over Liverpool, he may need a little more time on the sidelines. Liverpool is a big match, a match against a direct competitor for the top four but nothing is decided.
"In these types of games, when the pressure is on you, you just be yourself and I think that's what seems to happen in these games and the team seems to react well, when maybe we don't react as well in other games".
During his seven years at United, the Champions League is the only major trophy to elude Young, but he insisted that Mourinho's team can win the competition this season if they overcome Sevilla.
"I can imagine that if we lose against Seville on Tuesday everyone will have forgotten what we did in the last couple of weeks", he said.
Sevilla defender Clement Lenglet, meanwhile, believes his side are ready for the Red Devils and warned that United will see the best of the La Liga side if they score first. Tall, strong - the result of the intensive strengthening work demanded of him by Sinisa Mihajlovic during his first few months in Europe at Sampdoria - and quick, he carries the ball elegantly yet powerfully, able to subtlety adjust his trajectory at pace to open up space.More news: Colombia vote result could dent leftist's presidency bid, pleasing market

As you walk down the corridor more images detailing United's European adventures are displayed.
"Even if Paul Pogba was fit I don't think he would get in the United team, as he has suffered from the confusion that Alexis Sanchez's arrival has brought to the team". "I don't know what Real Madrid's intentions are, but if they were (thinking of De Gea) they should think of another player".
"He was getting minutes and getting experience and the best way to improve is to be on the pitch".
"He doesn't have to (speak to me)", said the forward.
After the shambles of Arsenal's last home game in this competition, when they almost blew it against Ostersund, Arsene Wenger will play a strong line-up with a free weekend to follow.
Lionel Messi had a nice rest at the weekend to be ready for this one, so I don't give Chelsea much hope at all.
"Right now, I'm probably not learning the most on the pitch", Rashford said.
