Radamel Falcao has left Atletico Madrid to become the latest superstar to join the ranks of AS Monaco as the principality club prepares to rejoin the French top-flight for the first time in two seasons. The 27-year-old Columbian striker has signed a five-year contract worth an estimated 50-million euros. Falcao follows closely in the footsteps of fellow new recruits Joao Moutinho and James Rodriguez from Porto and the former Chelsea and Real Madrid defender Ricardo Carvalho.
