Nigel Clough has warned Kris Commons he must be consistent if wants to earn a new Derby deal.
Fans' favourite Commons, who was frustrated by hamstring problems last season, is out of contract with the Rams at the end of the campaign.
The midfielder produced a superb display against Middlesbrough on Tuesday evening, notching two goals to help see off the visitors 3-1.
But County manager Clough insists that performance alone will not be enough to win the 27-year-old a new contract.
"He still has eight months remaining on his contract and there have been no talks about a new one yet," Clough told The Sun.
"He is not going anywhere yet but we will have to see what develops in the next few months.
"We will have to see if he can produce something more like that on a regular basis.
"The thing with him is that he has to be more consistent with his displays.
"He has to put a run of performances together and get on the pitch more often.
"We don't just give up contracts easily. The point is that you have to earn contracts at any club."
Commons, who arrived at Pride Park in 2008, will be free to talk to clubs in January if Derby fail to agree a new deal with the player.
