Pogba addressed a potential move to Barcelona while away with France over the international break and has told team-mates he wants to leave Old Trafford.
The United boss claimed he was unsure what Raiola has been engineering behind the scenes ahead of today’s visit to Watford.
‘If I watch Mr Raiola on the screen saying the players wants to leave, and that he is organising a way for him to try to leave or so on, then I will believe,’ Mourinho said.
‘At this moment, I am in the dark. The only thing that is clear for me is that the player never - never in all these days we are together - he never told me that he wants to leave.
‘I also need the agent to tell me or tell you in a way that I can see.’
Sportsmail has reported that Raiola held talks with Barcelona over the summer and Pogba’s situation has further clouded United during a difficult start to the season.
Mourinho added: ‘If he doesn't tell me he wants to leave, it's because he wants to stay. That's my conclusion.’
