Paris: Arsenal could be fined following crowd disturbances during their midweek Champions League clash with Galatasaray as European football`s governing body UEFA confirmed Friday disciplinary proceedings had been opened against six teams.
Galatasaray, Feyenoord, Standard Liege, Basel and Borussia Dortmund could also face sanctions after their supporters threw flares onto the pitch during games on Wednesday and Thursday.
Several flares were thrown onto the pitch from the section containing the 3,000-strong band of travelling Galatasaray supporters at the Emirates Stadium, causing the Group D match against Arsenal to be briefly halted.
Police confirmed there had been six arrests, two of which were for entering the ground with flares.
The north London club went on to win 4-1.
UEFA`s disciplinary body will study the cases on October 16.
