Besiktas hosted Napoli in the Champions League on Tuesday night and it can surely come as no surprise that there were several incidents of fan violence in Istanbul ahead of kick-off.
Turkish media outlet Tribun Dergi reported that a Napoli fan had been stabbed in the buttocks, sharing a photo and a video from the metro station.
In the video below a group of Besiktas fans can be seen attacking the Napoli ultras in a metro station.
The match ended 1-1, with goals coming from Ricardo Quaresma and Marek Hamsik.
