The former Cameroon coach has praised the powerful midfielder, but is having doubts about the 24-year-old's defensive abilities amid speculation linking the player with Barcelona
The 24-year-old has been linked with a move to Barcelona this summer, and his former international coach has plenty of positive words about Song, even though he's not convinced with the midfielder's defensive abilities.
"He has a very impressive physique and is a great guy. He is a very good player and is unlike any other player," Clemente told RAC-1.
"Song is a much better player in attack than he is defensively, though."
Clemente worked with Song during his spell in charge of Cameroon from August 2010 until October 2011. The powerful midfielder has a contract with Arsenal until the summer of 2015.
