Aitor Karanka says the £6m arrival of Rudy Gestede at Middlesbrough could lead to Jordan Rhodes' exit from the club.
Rhodes has made just six appearances for Boro this season - four of them off the bench - and has scored just six goals in the 11 months since his £9m switch from Blackburn Rovers.
Asked if Rhodes and other players could leave during the winter transfer window, Karanka replied: "Yes, if the right offers arrive and the players want to leave.
"I have said always that I am here to help everybody who wants to leave always when we receive the right offer because it is the market and to buy players, we need to sell.
"If one player wants to leave and the right offer arrives, I will help them."
Rhodes was much in demand when Boro swooped for him, but he and fellow frontman David Nugent have looked surplus to requirements for some time.
Karanka is hoping Gestede's capture from Aston Villa can help increase his side's firepower with the promoted club having managed just 17 goals in 20 league games to date.
He said: "I think he's a really good player for us. He gives us something different, he gives us things that we can't (do) at the moment and I am really pleased because he was here the first day that he could be here.
"I am really pleased because with him, we are adding a good player and a good person."
Gestede is likely to go straight into the squad for Sunday's FA Cup third round clash with Sky Bet Championship Sheffield Wednesday, although is unlikely to start.
In the meantime, the club will continue to work on its remaining targets to further increase the potency and creativity available to Karanka.
He said: "I think we need to improve the attacking position, and I hope we can bring in someone on the wings."
