The Portugueseman, who will take over from countryman Paulo Fonseca at the end of the season, has a long history of working with African talent.
Ohene Gyan has been causing a stir in the Roma U19 squad and may be offered a chance by Mourinho,
who enjoys working with African players.
The 18-year-old has two goals in three starts for the Giallorossi in the Primavera Championship and is tipped for greatness.
“The selection of José is a big step in creating a long-term and consistent winning culture in the club,”
said club president Dan Friedkin and vice-president Ryan Friedkin.
This might pave the way for Ohene Gyan to progress from the club’s academy to play first-team football.
Mourinho previously worked with Benni McCarthy, a former South African international,
at Porto, where they both won the UEFA Champions League.
He brought Didier Drogba, Michael Essien, John Obi Mikel, and Salomon Kalou to Chelsea.
Mourinho signed Sulley Muntari and gave McDonald Mariga chances during his fruitful spell at Inter Milan.
When Mourinho arrived at Manchester United, he signed Villarreal defender Eric Bailly,
who was relatively unknown in Ivory Coast.
