Having been blown away by rivals Manchester City, who are 19 points ahead of the chasing pack, United moved four clear of third-placed Tottenham with one game remaining to seal the merest of consolations.
United goalkeeper David de Gea, meanwhile, was untested as he ensured he will collect the Premier League's Golden Glove for the first time by recording his 18th shutout of the season.
"We came second. I am not totally happy, that is not my nature".
"I am not critical of the performance [against West Ham] at all".
"Romero plays on Sunday because he deserves that and some other players are going to play because we as a team achieve the second position and we, as a team, are going to play the FA Cup final", he said. It's hard to believe that the in the first game of the season we beat this team 4-0.
But Jose, in his interview, seemed confident that the club record signing will stay put at Old Trafford, beyond the end of the season, stressing on the fact that neither the club nor him want to let Pogba leave.
"The next evolution? Maybe I will see you in a few years and you will certainly have a European league over the weekends", he said.
Lukaku is expected to be back in time for the FA Cup final against Chelsea, and he can't return soon enough because, without him, there was no presence beyond the West Ham centre backs. "We had to get the players in order a little bit after we came in, and we have done that".
West Ham forward Marko Arnautovic has expressed his desire to carry his good form for the Hammers into next season.
The second half picked up precisely where the first had left off with United in search of an opener.
Mourinho deployed his side in a 3-5-2 formation with a surprise pairing of Alexis Sanchez and Jesse Lingard starting up front for the visitors.
A sliced clearance from Chris Smalling nearly gifted Arnautovic another chance five minutes later, but the Austrian could not readjust his body in time to turn Aaron Cresswell's cross on target.
Adrian was again on hand to keep out Lingard's strike.
