Manchester United are interested in strengthening their forward options with Bordeaux starlet Malcom, reports The Times.
The Brazilian youngster, 20, has shone for Bordeaux so far this season, scoring seven goals and adding four assists in 16 games.
And with Henrikh Mkhitaryan seemingly on his way out, Mourinho is eyeing an attacker with pace to come in and play on United's right side.
Both Anthony Martial and Marcus Rashford prefer operating from the left, but left-footed Malcom is quite the opposite.
And with Mourinho said to have £80million to spend next month as he looks to continue trying to push runaway leaders City, he may add Malcom to his attack.
