Manchester United will not consider selling Diogo Dalot while he is on-loan with AC Milan.
Dalot has played every minute of their Europa League campaign so far this season, bagging a goal and an assist in their 3-0 win over Sparta Prague.
ESPN says there is no option to buy as part of the loan deal and United will reject any attempts to make the move permanent in January.
Dalot is said to be 'highly-regarded' by manager Ole Gunnar Solskjaer, who views the move to Milan as a way for the 21-year-old to further his development.
His current deal at Old Trafford does not expire until 2023 and United do have the option to extend it for a further year.
