The Spanish international is understood to have missed-out on a 40-million euro move to Madrid after the documentation from Manchester didn't come through before the close of the La Liga transfer window.
Meanwhile, there's going to be plenty of other transfer dealings today, with the Premier League window set to close at six o'clock this evening.
Man United will be hoping to complete the capture of French striker Anthony Martial from Monaco while Irish international Jonathan Walters will be hoping to move to Norwich after he handed-in a transfer request to Stoke late last night.
