Former Arsenal and Chelsea midfielder Lassana Diarra is a target for Manchester United.
Le 10 Sport says Mourinho will attempt to sign Marseille midfielder Diarra if he takes over at Manchester United.
Mourinho worked with Diarra, now 31, at Real Madrid, and is keen on a reunion.
As well as spells with the Gunners and Blues, Frenchman Diarra also represented Portsmouth during his previous stint in the Premier League.
