Manucho will join Panathinaikos on-loan for the rest of this season after starring for Angola in the African Nations Cup, Mourinho says: "If you asked me whether I believe one day he will play for Manchester United I have my doubts.
"I do not know if he will progress so well that he can play for one of the best teams in the world.
"But he is clearly a very good talent. He's ready to play in European football.
"He will go to a good club in Greece, with a good coach who I believe can help him in his development as a player."
