Wes Brown's Manchester United future could be in doubt after the defender rejected a new four-year contract.
Brown has 12 England caps to his name
The 28-year-old, who is out of contract at the end of the season, has been at the club since leaving school.
"He has not agreed anything, which is entirely up to Wes, we feel we have made him a good offer," said United boss Sir Alex Ferguson.
"We've met with his agent. They've rejected our last offer so that is the end of it. We won't be going back."
Brown has been a regular for United this season, filling in for long-term injury victim Gary Neville at right back.
Sir Alex did not say if he would be willing to sell Brown in the transfer window, and admitted he could lose him on a free transfer at the end of the season - but would not be held to ransom.
"It's a possibility. It would be a disappointment," he said.
