Owen Coyle admits Bolton are braced for further enquiries for Gary Cahill in January, and has called for any clubs interested in signing the England international defender to make their bids early in the transfer window.
The 25-year-old is out of contract at the Reebok Stadium at the end of the season, which has led to plenty of speculation about his future.
Cahill was the subject of a derisory offer from Arsenal in the summer, while both Chelsea and Tottenham have been linked with £7million offers for the Trotters star in the New Year.
"If something comes in then I think for Gary and for everybody it is going to be better sooner rather than later," said Coyle.
"We all know the further you get into the window, the more it is fraught with danger."
The Bolton boss is confident that Cahill will not be unsettled by continued speculation, and has called for him to help his teammates in their bid to stave off the threat of relegation.
"You could have a gut feeling and get it totally wrong but whatever happens in January we will deal with it accordingly," he continued. "Until then we have to make sure Gary's playing at the top of his game. And if he is then he'll show everybody, as we already know, how good he is.
"I would imagine then, if he is performing out of his skin, there will be a clamour of clubs for him because of the situation.
"Between now and then, he has to be focused and doing his job to the best of his abilities, as he always has done, both for himself and his international aspirations, and the team."
