Wayne Rooney's penalty at the end of the first half - his 252nd goal for the club - gave United the lead before Gylfi Sigurdsson scored on a sublime free kick 10 minutes from time to earn a point for Swansea. Of the Europa League match, Mourinho said: "We will give everything on Thursday".
With the first leg of the Europa League semi-final against Spanish side Celta Vigo next up on Thursday, the injury to Bailly could not be more unfortunate with no senior centre-backs now fit. "We are exhausted, if some people want to analyse the performance itself, its one thing".
"You can not isolate the performance from the context and that is nine matches in April, the last match a derby on Thursday evening and now a match on Sunday at 12 o'clock". The match marked United's ninth outing in April alone as their busy schedule to conclude the season continues. You can not be punished because we play the League Cup final, you play the final and then you have to play the (other) game in midweek. "And hopefully Crystal Palace doesn't need the game to stay in the division, because it would be very bad for us to play the game with the Under-23s".
Jose Mourinho's injury-hit squad knew three points would be enough to see them up to third place in the English Premier League, ahead of Liverpool and Manchester City. Of course, they did not play the last match. "Whether we go to the final or not doesn't matter, I am really happy with the guys".
Injuries to Bailly and Marcos Rojo could leave United fielding a makeshift defence at Balaidos and Mourinho even claimed he would not be disappointed with his players if they now fail to reach the Europa League final.
Chris Smalling and Phil Jones remain injured and Mourinho said, when asked about their progress: "I prefer not to speak". I prefer to speak about Juan Mata giving everything to be available. I don't think they will play, that is my personal opinion. I'm grateful for that. Shaw was replaced by Antonio Valencia after just eight minutes with what looked to be a knee injury.
That decision came after Marcus Rashford went down under a challenge from visiting goalkeeper Lukasz Fabianski, an incident that infuriated Swansea manager Paul Clement. "You could say he has dangled a leg to get the contact, but he is (going) down before that, before there is any kind of contact". I'm saying deceived. It's the word I've chosen.
