United announced the arrival of teenage winger Diallo on Thursday, with the Ivorian signing a four-and-a-half-year deal running until the summer of 2025.
With a work permit secured, the club has now unveiled Diallo as their own player and he wasted no time in pulling on a United shirt for the first time.
Diallo posted a photo on to his Instagram story picturing himself wearing the club colours with this season’s shirt.
