Manchester United are among clubs keen on PSV Eindhoven midfielder Hirving Lozano.
Lozano was a revelation for Mexico at this summer's World Cup and was linked with a move to Barcelona. However, the market shut last month with Lozano still a PSV player.
Barca have since pulled back their interest, with four major clubs now following his progress.
Inter Milan, Juventus, Manchester United and Atlético Madrid have all had scouts watch Lozano this season.
Interestingly, United scout Mark Prizant was in Houston on Sunday to see Lozano and Mexico lose to Uruguay.
