Diego Buonanotte's form with River Plate has seen him being linked with a move to England.
The Argentine playmaker has recovered from a serious car accident last year to return to his best form for River this season.
Corriere Dello Sport says up to six European clubs have been in contact with River about Buonanotte's asking price.
Juventus, Arsenal, Fiorentina, Manchester United, Benfica and Spartak Moscow are all ready to battle for the 22 year-old's signature.
