Speaking with Marca, Bale was happy to discuss the rumours, insisting no formal bid has been made.
He declared: "Manchester United? The truth is that I have not read anything about it. I am a British player so logically they always associate myself with a return home during each mercato.
"It happened with (David) Beckham, and with other Englishmen who came to Spain. Nothing new. I am happy to play Real Madrid, an interest is an interest but if there is nothing concrete, no offer, there is not much to say."
