Southampton are chasing Legia Warsaw star Ondrej Duda.
The Sun says Ronald Koeman has identified the central midfielder as a replacement for departing French ace Morgan Schneiderlin.
The Slovakian international helped Legia Warsaw achieve their second successive Polish league title, and featured in their impressive Europa League campaign.
Schneiderlin looks set to leave St. Mary's this summer with Premier League trio Arsenal, Manchester United and Tottenham all vying for his services.
