Crystal Palace are still pushing to sign Arsenal forward Eddie Nketiah.
Patrick Vieira is keen to strengthen his squad further following the recent signing of midfielder Will Hughes from Watford, and has targeted a new forward.
Talks are continuing over a fee, but a gap remains between the two clubs’ respective valuations.
A German club are also in the mix for Nketiah, who has entered the final year of his contract at the Emirates.
Talks over a new deal at Arsenal earlier in the window failed to find a resolution.
