Swiss champions Young Boys concluded a forgettable Champions League campaign without a point after suffering a 1-0 home defeat at the hands of Red Star Belgrade.
Guelor Kanga came off the bench to score the winner for the Serbian side as he rifled a Seol Young-woo cutback past Young Boys goalkeeper Marvin Keller and into the top corner with 21 minutes left on the clock.
Red Star began the game on the front foot but the game remained goalless at the halfway point with captain Mirko Ivanic and Cherif Ndiaye missing gilt-edged chances for the visitors.
Andrija Maksimovic fired wide for Vladan Milojevic's side before Kanga scored four minutes after coming on to inflict an eighth straight defeat on Young Boys in the competition.
Red Star, meanwhile, are also out and finished their campaign with six points from eight games.
