The 25-year-old midfielder, who joined the Red Devils from Juventus in the summer of 2016 for a transfer fee reported by BBC Sport to be worth £89 million, has struggled with form and fitness issues this season.
And Mourinho has continued to go on the front foot over United's period of transition, with a 16-point gulf separating them from neighbours and Premier League leaders Manchester City.
Mourinho came in for significant criticism over United's tactics in the wake of that defeat and he responded with a 12-minute tirade in his news conference before the 2-0 FA Cup win over Brighton.
He declared: "I think that compared to the Euros, Griezmann did something flawless, he showed his qualities by being a key player of this team of France". Maybe not the same as all the players but he is not outcast.
"I understand the sadness of being knocked out in the Champions League, but I don't understand anything more than that", Mourinho told CNN.
France captain Hugo Lloris highlighted Pogba's injury problems as a reason for his lack of impact on the pitch this season.
Meanwhile, Deschamps said he had talked with Pogba about his situation at Manchester United and found the situation to be "complicated", adding that "Everyone is talking about Paul now. I have no doubt that he will be ready for this huge competition and show his best side".
