Manchester United manager Louis van Gaal has blocked Adnan Januzaj from moving to Paris Saint-Germain, according to the player's agent.
The winger had a breakthrough season last year but he has started just five times under Van Gaal this campaign, prompting speculation over his future.
The French champions reportedly made an attempt to sign Januzaj last summer before he turned them down and signed a long-term contract at Old Trafford, but PSG have come back in for him this month.
His agent, Dirk de Vriese, told reporters: "Yes, PSG have shown themselves to be interested this winter. They directly contacted Manchester United for information. But Louis van Gaal announced that [Januzaj] cannot leave this winter. Not as a permanent transfer nor as a loan.
"The coach considered him as an important player for squad. He is counting on everyone. It seems like a definitive decision, I don't think that it can change."
Januzaj is yet to score this season.
