Bolton manager Owen Coyle admits he may have to consider selling Gary Cahill if a suitable offer is received in January.
The England centre-back was a summer target of Arsenal before Arsene Wenger decided to instead sign Per Mertesacker from Werder Bremen for £8million.
Reports have suggested Wenger could renew his interest in Cahill, who is thought to be valued at £17m by Bolton, while Tottenham failed in attempts to complete a deal.
Coyle would prefer to keep his star defender, but the Bolton boss acknowledges factors may mean his club's hierarchy will have to think about a sale.
"That is something that will be seen to be the case in January," Coyle said at a pre-match press conference ahead of Saturday's trip to West Brom when questioned about Cahill's future.
"I would love to work with Gary Cahill every day of the week for as long as I could because he is a top player and a fantastic young man.
"Again, sometimes things are taken out of your grasp. We will wait and see what January brings.
"But, for this moment in time, what's more important is we continue to improve as a team and continue to pick up points in the Premier League."
