Nigel Clough admits he is unsure whether Kris Commons will sign a new deal at Derby, but the situation should sorted after the game with Nottingham Forest on Saturday.
The top-scorer's current deal expires in the summer and it is thought he is a target for Old Firm rivals Rangers and Celtic.
Clough has previously spoken of his hopes that contract talks can be resolved soon, believing they could be affecting the player, and the Derby boss is eyeing a resolution at the weekend.
He told the Derby Telegraph: "It has swung several ways in the previous few weeks and I wouldn't like to guess the outcome at this point.
"We were hoping it was getting closer (to being signed) but negotiations can all of a sudden take a twist or turn and set things back.
"I think after Saturday's game it will get sorted, one way or another."
Meanwhile, Clough revealed the Rams are close to landing Notts County's Ben Davies and are still hopeful of signing Leicester City striker Martyn Waghorn on loan.
A fee worth up to £350,000 is thought to have been agreed with the Magpies for Davies, who is expected to sign in time for the Forest clash.
But the bid for Waghorn depends on the fitness of Foxes striker Darius Vassell, who has a hamstring strain.
Clough said: "We are getting closer to Ben Davies.
"We are in the hands of the other clubs as well and we will get them in as quickly as we can."
He added: "We are still talking to Leicester (about Waghorn) but it is about their injury situation.
"We just hope he (Vassell) will be OK in time for Saturday. If he is OK, we would love Martyn in for Saturday's match."
While admitting it is not ideal getting the players in late, Clough believes they could provide a spark against Forest.
He added: ""It is not ideal to bring them in late before a key game. We would like them in training on Friday morning, which we are looking to do and then at least they get a degree of familiarity so they are not just reporting on Saturday morning for the game.
"Both players have been playing reasonably regularly. Martyn came on against Manchester City in the FA Cup on Tuesday night and I'm sure both players will be champing at the bit to get on the pitch.
"We are looking for a boost, a spark. Two or three new players might just provide that."
