Chelsea have shown interest in signing left-back Ajax Nicholas Tagliaviko.
Tagliaviko has been crowned 25 times for Argentina and could become the second Ajax player to move to Stamford Bridge ahead of the new season following the arrival of Hakim Ziyech.
The 27-year-old, who scored five goals and provided five assists in 38 games for Ajax last season, is currently under contract through the summer of 2022.
Chelsea can look to Tagliavico, who joined Ajax in 2018 from Independiente in his homeland, as a replacement for main left-back Ben Chilwell, the England international.
Chelsea have so far failed to come to terms with Leicester regarding Chilwell, and the two clubs were further apart in the assessment, although the Foxes are believed to have softened their original demands for an £ 80 million transfer fee.
Chelsea are also monitoring the availability of Real Madrid Sergio Reguilón, who was voted the best left-back in the Spanish League last season, while on loan to Sevilla.
