Manchester United and manager Louis van Gaal are too stubborn, according to ex-Real Madrid man Francisco Buyo.
Former Real Madrid goalkeeper Francisco Buyo warned Louis van Gaal and Manchester United not to be stubborn over David de Gea's potential transfer to the La Liga giant.
As the De Gea transfer saga continues, Van Gaal has said the United goalkeeper will not be sold despite continued interest from Real.
With the 24-year-old Spain international entering the final year of his contract, the Premier League giants risk losing him for free come season's end.
