The Chilean striker, signed for £4million from Universidad de Chile last summer, has not featured for United in a senior game yet but made his Premier League debut on loan at Wigan in January when he scored against Sunderland.
However, the loan deal has not panned out and the 18-year-old striker has grown frustrated after only getting onto the pitch for three minutes of stoppage time in the past two months at the DW Stadium.
Wigan boss Roberto Martinez admitted he only wanted Henriquez as cover for Aruna Kone while his main striker was at the African Cup of Nations and it appears as though the on-loan starlet's chances will remain limited until the end of his current stint.
Chile coach Jorge Sampaoli picked Henriquez for his side's most recent World Cup qualifiers but he is unlikely to keep him around the squad next season if the teenager remains inactive for his club.
Henriquez is hoping to persuade Sir Alex Ferguson to allow him to go on loan again next season - to a mid-table La Liga or Championship club - where he could get the opportunities to develop his game and stay in the national team.
The striker's plight highlights a bigger problem that United have when they loan talented players out for experience and suggests Ferguson has not been matching them to the right clubs.
While Henriquez, Fabio and Kiko Macheda have all suffered on loan at Wigan, QPR and Stuttgart respectively this season, Chelsea's young players have clocked up an impressive number of appearances away from Stamford Bridge.
Thibaut Courtois, 20, has started all but one of Atletico Madrid's La Liga matches while Romelu Lukaku and Kevin de Bruyne have made over 50 appearances for West Brom and Borussia MG between them.
Jeffrey Bruma, Josh McEachran and Patrick van Aanholt have been regulars when fit for their clubs in Germany, England and Holland this season while Lucas Piazon has made seven appearances for Malaga since joining them in January, two in the Champions League.
