The hard-hitting full-back had a stint in Turkey with Fenerbache and thinks the nine-time European Cup winners are the favourites in the tie, but will not write off the Turkish champions on their own turf.
"In terms of tactics, depth and quality, Madrid is one step ahead," he continued.
"The second leg may become very difficult [for Madrid] because the atmosphere in the stadium is impressive.
"Galatasaray could eliminate Real Madrid in Istanbul."
