Paris Saint-Germain forward Neymar is reportedly a transfer target for Manchester United, who are willing to go as high as £200m with their offer.
The Brazil international is said to be seeking a move away from the Parc des Princes, just a year after arriving in a record £198m switch from Barcelona.
According to The Mirror, however, United are also lining up a sensational swoop and are prepared to match the amount offered by Real.
The report suggests that, as well as making it clear they will pay the world-record sum, the Red Devils can also afford the 26-year-old's £30m-a-year wages.
Neymar scored 25 goals and set up 16 more in a combined 27 Ligue 1 and Champions League outings for PSG prior to sustaining a season-ending injury in February.
