The XI is selected by UEFA's Technical Observer Group and, although it will be scant consolation to Casemiro and Bruno Fernandes after the 1-0 defeat to Tottenham Hotspur in Wednesday's final in Bilbao, the midfielders' performances throughout the campaign have been recognised.
United had been unbeaten in Europe this term, until Brennan Johnson's effort separated the sides at San Mames, and the result probably helped Spurs have a total of four men in the representative team.
Casemiro scored in both semi-finals against Athletic Club and displayed his experience and quality during the run, including earning a penalty and then providing both assists in the extraordinary comeback against Lyon at Old Trafford in the last eight.
