Sliven's third consecutive season in the top flight was less successful, however. Dimcho Nenov was appointed as coach for the 2010-11 season. The team finished in last place, with only 4 wins, 7 draws, and 19 losses. This only earned the team 19 points, 6 points behind the 14th place, which would at least qualify them for the relegation playoffs. Sliven managed three home wins, and only one away win, against fellow relegated Akademik Sofia. This relegation ended their three year stay in the A PFG.
