Eagles bet bottom-club Kocaeli 4-2 by coming from behind in the opening match of Week 10 of the Turkcell Super League.
In spite of starting off the game with well organized wing attacks, Besiktas fell 1-0 behind unexpectedly with a 15th minute goal by Taner Gülleri thanks to deadly mistakes of home side and put Kocaelispor to an early lead.
Just 1 minutes later, Semavi added another who cleverly netted the ball with header to Taner's cross from close range to give visitors a valuable 2-0 advantage.
Despite falling behind so early, Besiktas took the control of the game and pulled one back with Nobre’s 30th minute goal.
After receiving a long-range pass from Tello, Filip Holosko dribbled so fast and found himself in a one on one situation with the goalkeeper and his finish leveled the score at 43-minute mark.
In the second half, Besiktas carried the game completely into visitors half of the field. Matias Delgado curled a classy shot in the right-hand corner, leaving Serdar Kulbilge helpless that gave Eagles a much needed 3-2 lead for the first time in the game at 67th minute.
After perfect passing with Delgado, Mert Nobre rewarded the fourth goal who fired a 72nd minute bullet from outside the box.
78th minute substitute Bobo redirected Serdar Ozkan’s clever pass with brillant shot into Kocaelispor net for a 5-2 Besiktas lead in the dying moments of the game. That goal was the 50th of Da Silva Bobo in the offical games with Besiktas.
Black Eagles raised their point to 21 with that 5-2 victory.
