Monaco enjoyed success in the 1970s and late 1980s during the managerial tenures of Lucien Leduc and Arsène Wenger, during which the club was amongst the leading lights of European football. Monaco's traditional colours are red and white, and the club is known as Les Rouge et Blanc (The Red and White). Monaco is also a member of the European Club Association. In December 2011, two-thirds of the club was sold to an investment group led by Russian billionaire Dmitry Rybolovlev. With Rybolovlev's financial backing, the club quickly returned to Ligue 1 and brought in several top-rated players, including Radamel Falcao, João Moutinho, James Rodríguez, Ricardo Carvalho, Éric Abidal, Jérémy Toulalan.
