Former Cameroon coach Javier Clemente has hailed Arsenal midfielder Alex Song and believes that he is "unlike any other player".
Clemente worked with the 24-year-old during his spell as the Cameroon boss between August 2010 and October 2011, and was impressed with his abilities.
"He has a very impressive physique and is a great guy," Clemente told RAC-1. "He is a very good player and is unlike any other player.
"Song is a much better player in attack than he is defensively, though."
Song has been linked with a move to Barcelona this summer.
