Owen Coyle says Gary Cahill's representatives remain locked in talks with Chelsea, meaning he could figure for Bolton against Manchester United on Saturday.
A deal to take the England international to Stamford Bridge is edging closer, with the Blues having agreed a fee with the Trotters.
It was anticipated that a move would be pushed through this week, but the clock is ticking on Chelsea's effort to have everything put in place by the weekend.
With personal terms proving to be something of a stumbling block, there is a chance that Cahill will line up for Bolton in their meeting with North West rivals United at Old Trafford.
"Dialogue continues between Gary's agent and Chelsea," said Coyle.
"We accept it has probably been long-drawn. It is over two weeks ago that we agreed a fee.
"But sometimes that is the nature of football business. It can take that period of time.
"Gary is a Bolton player and until I hear something different in terms of negotiations being concluded between both parties, he will be in line to play against Manchester United."
It has been suggested rival suitors have made their interest in Cahill known, however, this is news to Coyle, who insists Chelsea remain the only option for the 26-year-old at present.
"If other clubs are linked with him it is just speculation," added the Scot.
"We have agreed a fee with Chelsea. I have had no dialogue with any other club.
"We recognise it is the silly season but I don't deal in rumour. I only deal in fact.
"The fact is we have agreed a fee with Chelsea. We have not spoken to anyone else. That is where we are."
