The Sunday Mirror reports that United chiefs believe they have a chance of signing the 25-year-old in the final 72 hours of the transfer window.
United’s hopes of signing Bale could be given a boost if the Welsh wizard is the target of fan abuse in Real Madrid’s home opener.
Bale was abused by the boo-boys of the Bernabeu both on an doff the pitch last season.
The negativity towards Bale could persuade Real Madrid president Florentino Perez to cash in on the former Tottenham star in a £95million deal.
United are desperate to bring Bale to Old Trafford after having failed to make a headline signing so far this transfer window.
