Medipol Başakşehir coach Abdullah Avcı upsets Şenol Güneş once again.
Beşiktaş has no luck against Başakşehir in another game and misses the opportunity to share in the league leadership.
Başakşehir grabbed the 3 points with the sole goal from Epureanu in 18th minute.
The game was twice hard for Beşiktaş since the Black Eagles were on the pitch without Potrugese maestro Ricardo Quaresma.
After the loss, Beşiktaş fell 6 points behind the top of the league.
