#3 Thibaut Courtois
Having previously donned the colors of city rivals Atletico (even going as far as to mock Real during title celebrations in 2013), the Belgian international embarked on a bitter campaign to join the Spanish giants last summer.
Personal strikes, refusing to turn up for training - Courtois spared no punches in trying to force through the move and finally got his wish as Chelsea caved in to his demands and agreed a transfer with Real Madrid for his signature.
The 26-year-old's signing was seen in many quarters as a rather unnecessary one, as despite the fact that he does not get as much accolades as he deserves, Keyor Navas is more than a decent goalkeeper in his own right, contributing his fair share to Real Madrid's successes in recent years.
With more glaring problems in other sectors, the goalkeeping area was the least of Real's worries, and quite why the club sanctioned the purchase of Courtois beggars belief.
Zidane is likely to stick with his tested and trusted choice in Keylor Navas (evidenced by his immediate restoral to the starting lineup in Zizou's first match in charge) and the fact that Courtois has too much pedigree and high profile to remain a second choice means that it might be more profitable for Real to cash in on him.
