Millwall manager Kenny Jackett says Sunderland have not been in touch about midfielder Liam Trotter.
The Black Cats have been linked with a move for the 22-year-old, who only joined the Lions permanently from Ipswich Town this summer.
"I've had no contact from Sunderland, or any calls," said Jackett. "People did tell me that was in the papers and I have seen it but we've had no contact from anybody at all about Liam.
"I wouldn't welcome any move and we are not under any pressure to sell any of my players."
