Bale is expected to exit Real Madrid at the end of the season.The Wales star has endured two years of injury problems and Real are keen to replace him.
Manchester United have kept Bale on their radar ever since he left Tottenham for Real in 2013.
And reports in Spain claim the Red Devils are set to get their man.
According to outlet Diario Gol, Bale has a pre-agreement in place to join United at the end of the year.
Tottenham are also reportedly keen on bringing their former star back to north London.But United have the financial muscle to get the deal through.
Bale, 28, is said to have agreed to join United at the end of the campaign so long as the two clubs involved can settle on a transfer fee.
And that is where things could get tricky.
Diario Gol claim Real president Florentino Perez wants a minimum £78.9m (€90m) fee for the Southampton academy product.
