Sierra Leone striker Kei Kamara has retired from international football with immediate effect because he is unhappy with issues relating to the national team.

The 35-year-old, who plays for MLS side Colorado Rapids, took the decision on the eve of Sierra Leone's opening 2021 Africa Cup of Nations qualifier against Lesotho.

He was one of 15 overseas-based players selected by the Leone Stars coach Sellas Tetteh for the Lesotho game and Saturday's qualifier in Benin

"I can confirm that I have retired from international football because I'm unhappy with the progress of national team," Kamara told BBC Sport.

"I've been with national team since 2008 and there has been no improvement, no plan for the direction the national teams should go from the youth level to senior level."

The former Norwich and Middleborough forward, who has now been replaced by locally-based player Sallieu Tarawallie, cited Tetteh as one of the reasons for his decision.

"Coach Tetteh is a good man and has good intentions. But he's an old man who I do not believe is able to really improve us and to move us forward." Kamara continued.
