(GSM) Besiktas suffered their first defeat of the season on Saturday, a painful one at that as the local derby with Istanbul BB ended 0-2.
After taking three points from their opening match last week, Besiktas expected to do the same against a generally much weaker Istanbul BB side.
But the hosts failed to score in the opening half in Turkey s largest city, and it was in fact Istanbul BB s Iskender Alin to break the deadlock three minutes before the end.
The 26-year-old midfielder, who scored four goals in the entire 2009-10 season, went on to add another in added time for a surprise 0-2 result.
In the other match of the day, Sivasspor were held to a 1-1 draw at Antalyaspor.
