During the 2014 summer transfer window, Pérez brought in 2014 FIFA World Cup stars James Rodríguez, Toni Kroos, and Keylor Navas to Real Madrid for a combined cost of £95 million, as well as Javier Hernández on a loan deal from Manchester United. As a result of the mounting competition for starting spots and wage disputes, Ángel Di María left the club for Manchester United for a British record transfer fee of £60 million. Xabi Alonso also left during this transfer window to join Bayern Munich. In January 2015, Pérez demonstrated his success in the transfer market when Real Madrid signed the 16-year-old Norwegian Martin Ødegaard in competition with many of the big clubs in Europe, including Bayern, Barcelona and Arsenal.
