Manchester United have a buy-back option on Memphis Depay
Depay arrived at Manchester United from PSV Eindhoven in the summer of 2015 under Louis van Gaal but he struggled for form in his debut campaign.
And Mourinho has now sold the Holland international to Lyon for a fee believed to be £21.7million after playing him just eight times this term.
But the Red Devils boss reckons the 22-year-old has potential to one day make it at Old Trafford.
When asked about the buy-back option, Mourinho said: “Because potentially he’s a very good player.
"When Mr Van Gaal decided to buy him he did well, he knew him very well, he was very young at the World Cup, he had flashes of top quality, he was playing well in Holland.
"We know the Dutch league is not the same but he was showing very good things.
"He didn’t succeed in his 18 months but he’s very young.
"So I think it’s important for the club to have complete control in this talent and we wish he plays very well at Lyon and why not to come back because everyone here likes him.”
