Monaco forward Radamel Falcao has described former Atletico Madrid team-mate Thibaut Courtois as the best goalkeeper in the world.
The striker left Vicente Calderon - where the shot-stopper is spending his third consecutive season on loan from Chelsea - for Ligue 1 in the summer.
But on Thursday, Falcao is set to clash with Courtois when Belgium host Colombia in a friendly tie and the 27-year-old had nothing but praise for the Atletico No.1.
"He is a good friend," Falcao is quoted as saying by Nieuwsblad. "And he is the best goalkeeper in the world."
Thomas Vermaelen has warned his Belgium team-mates that dealing with the former Porto striker is going to be difficult, but says playing against South American opposition is great preparation for the World Cup, which both teams will be top seeds at.
"Playing against Radamel Falcao is a great challenge," the Arsenal defender said. "Falcao has been a goal machine.
"He plays for the opposition, which makes this game more interesting, especially for the defenders to try to prevent him scoring.
"Ahead of the World Cup, it is a very good idea for us to measure ourselves with teams from other continents."
