#3 Arsene Wenger
Arsene Wenger would be an unexpected replacement for Lopetegui, given the other candidates available to Real Madrid and the problems faced by Arsenal towards the end of Wenger's reign. The Frenchman's success during the first half of his time in London was nothing short of remarkable, with the 2004 Invincibles team regarded as one of the all-time great club sides.
Wenger brought a new attacking mindset to the Premier League, with the Frenchman always two steps ahead of Sir Alex Ferguson's Manchester United.
Part of the reason why Wenger's tenure came to an end involved the amount of power he had at the club. Arsene was in charge of the starting eleven as well as any transfer dealings. Stan Kroenke, however, decided not to give Arsene the sack despite his shortcomings in the league and cup competitions because of the financial benefits he brought in.
Fiorentino Perez will not give the former Monaco manager any such liberties, which would force Wenger to give his absolute maximum for the club. Although his reputation and attacking style would win over the hearts of the Madrid fans, he will need to adapt to ensure his team also defends well.
