Newcastle United are being linked to Estudiantes winger Benjamin Rollheiser as a summer signing.
Per TNT Sports and journalist Nicolas Latini, the Magpies have already put in a bid for the attacker.
The Magpies are eager to bring the 23-year-old to Europe and the Premier League.
The source adds that Newcastle hope to sign Rollheiser for around €10 million, but that may not be enough.
Estudiantes president and former Premier League star Juan Sebastian Veron has a much higher valuation.
The Argentine club are seeking a fee that would be around double of that offer from Newcastle.
