The France international left Lyon to join Madrid in 2009, the same summer in which the Red Devils sold Cristiano Ronaldo to the Spanish club for £80m.
And Aulas has revealed that the striker opted to move to the Bernabeu, even though the Premier League club had offered him a more lucrative deal.
“For a long time he wanted to play for Real Madrid, and when things began to fall into place we did not object,” Aulas told Canal+.
“Manchester United’s offer was superior, but he was given the opportunity to go where he wanted.”
The 26-year-old has scored five goals and made three assists for Los Blancos so far this season.
