Juventus and Valencia are battling over PSV Eindhoven pair Santiago Arias and Hirving Lozano.
PSV's Colombia fullback Arias has been expected to leave PSV this summer, while Mexico midfielder Lozano is courting interest from across Europe.
Cadena Ser says Valencia are chasing both South Americans for the summer market.
However, Los Che face competition from Italy, where champions Juventus are also interested in both players.
Lozano, 20, is a top target for Juve, while Arias is under consideration as a replacement for the departing Stephan Lichtsteiner.
