Besiktas stayed top of the Turkish Super Lig in dramatic fashion as they beat Bursaspor 3-2, while Fenerbahce hammered Gaziantepspor.
Demba Ba's stoppage-time free-kick completed a Besiktas fightback as they beat Bursaspor 3-2 on Sunday to stay a point clear at the top of the Turkish Super Lig.
Slaven Bilic's side fell behind when Cedric Bakambu put the fourth-placed visitors in front with a composed finish after racing clear 12 minutes in.
The prolific Ba struck 11 minutes later with a clinical strike and the Istanbul side were in front for the first time when Gokhan Tore found the back of the net with a stunning right-foot strike three minutes from time.
There was still plenty more drama to come, though, and Ozan Tufan looked to have salvaged a point when he volleyed home with 90 minutes played, only for there to be one final twist.
As Kerim Frei raced into the penalty area Sener Ozbayrakli tugged the substitute back and was shown a red card before Ba held his nerve to score his 22nd goal of the season from the penalty spot and secure all three points nine minutes into time added on.

Bottom-of-the-table Balikesirspor must have been braced for a hammering when Aykut Ceviker was shown a second yellow card just after the hour-mark, but they showed character and Ermin Zec scored a consolation 10 minutes from time.
