Gimnasia La Plata defensive midfielder Fabian Rinaudo is interesting Chelsea.
The Daily Mail says the Blues are not alone in coveting the 22-year-old, who has been compared to fellow combative Argentine Javier Mascherano.
Valencia are believed to have tabled a £5million bid for the 5ft 8in terrier, while Galatasaray plus Italian sides Catania, Napoli and Juventus have also shown interest.
Everton were also linked with Rinaudo last year and cash-strapped Gimnasia are ready to sell one of their star performers.
