Crystal Palace are interested in Liverpool forward Ben Doak, who is on loan at Middlesbrough in the Championship as they look for January reinforcements.
The Eagles are looking to add a left wing-back and an attacker to their squad to increase the options manager Oliver Glasner has for the second half of the season.
Doak has two goals and six assists in 21 appearances for Middlesbrough so far this season.
Liverpool have had offers for Doak with clubs in the Premier League and across Europe showing interest in the Scotland winger. Palace have had a £15m bid rejected, according to reports.
However, the bids so far for 19-year-old do not come close to what the Reds are looking for, with the Anfield club valuing him at about £30m.
Doak has helped Boro to fifth place in the Championship and are happy with how his stint at the Riverside club is going. They believe he has the quality to return and play for them in the future.
The Eagles have also been linked with Jobe Bellingham of Sunderland and RC Lens midfielder Andy Diouf, but one source has said a move for either midfielder is unlikely this month.
Elsewhere, Chelsea do have a recall option on Trevoh Chalobah, who is on loan at Selhurst Park but Glasner is "planning" for him to stay.
"Trevoh is doing very well for us and we are planning with him," the Austrian said after Saturday's 1-1 draw between the clubs.
