Crystal Palace are reportedly closing in on a free-transfer deal for Takehiro Tomiyasu after the Japan international impressed the club during a trial period, according to BBC News.
The Eagles are said to be satisfied with what they've seen from the versatile defender, who is currently a free agent, and a move now appears to be edging towards completion.
Palace are also understood to be weighing up a separate approach for Brighton winger Solly March, though that particular deal is described as being in its early stages.
Should the Tomiyasu switch be finalised, it would represent a shrewd piece of business for Oliver Glasner's side, bringing in a player with Premier League and Champions League experience at no transfer cost. March, meanwhile, remains firmly on Palace's radar as they continue to assess their options in the market, but no formal move has yet been made for the Brighton man.
