Crystal Palace are continuing talks for Lazio midfielder Daichi Kamada as well as Sunderland's Jobe Bellingham.
Palace are braced for offers for Michael Olise with Newcastle United and Chelsea pushing for the France U21 international while he also has interest from Manchester United.
Kamada, 27, failed to agree terms on a new deal with Lazio amid issues over a release clause figure of £17m.
The impressive Japan international will be a free agent and is keen to link up with Oliver Glasner, his former coach at Eintracht Frankfurt.
Palace still intend to pursue Jobe Bellingham also amid competition from Brentford. Bellingham, brother of Real Madrid's Jude has been a long-term target for Palace.
Birmingham City retain a 15 percent sell-on for Bellingham.
Palace are also signing Chadi Riad, the Real Betis centre back for £12.7m plus £1.7m in add ons, on a five year contract once he is back from international duty with Morocco.
