Pogba, 25, snubbed questions from reporters after Manchester United‘s midweek defeat by Juventus at Old Trafford in the Champions League.
However, the Frenchman appeared eager to stress it was not his decision.
“It’s not me. I can’t talk. I am not allowed to talk,” he said.
“I want to but I’ve been told not to talk. It’s not me.”
But United are adamant that Pogba hasn’t been slapped with a gagging order.
The club say there are no instructions to prevent Pogba from talking to the press.
It’s been a turbulent season for the World Cup winner after Mourinho stripped him of the vice-captaincy last month.
Pogba, the club’s record £89million signing, has proceeeded to criticise Mourinho’s tactics, saying they should be more attacking in games.
In other Old Trafford news, Express Sport understands United have got a two-man wishlist as they look at potential replacements for under fire boss Mourinho.
United would like former Chelsea boss Antonio Conte – or Juventus coach Max Allegri – to take over the Old Trafford hot seat.
But they have competition for Conte as Real Madrid and AC Milan could both be looking for a new head coach this week.
Julen Lopetegui faces the axe at Real if they lose the El Clasico game to Barcelona this evening and Conte is now free after leaving Chelsea in the summer.
He impressed in his first season at Stamford Bridge winning the Premier League but it all came apart after he fell out with the Chelsea board over transfers.
Mourinho has won himself some breathing space after a recent turnaround in fortunes but it’s likely that United will call time on his stay at the club in the summer.
