A second Turkish club are responsible after Besiktas fans lit a flare at Tottenham Hotspur, just one night after Gala supporters did the same at Arsenal.
Tottenham Hotspur could have banked a maximum three points earlier this evening, Thursday, as Spurs led their Europa League group game against Besiktas for 62 minutes and almost had the victory secured - yet former Chelsea striker Demba Ba stepped-up and converted a dramatic penalty one minute before the final whistle.
Currently third in Group C, the triumph would have been beneficial to the club's hopes of progressing into the latter stages of the competition as Tottenham play catch up in their next game, a White Hart Lane test against table-toppers Asteras Tripolis.
Before then, Spurs may have to answer to UEFA.
While it was Besiktas who marred the European game tonight because one of their supporters lit a flare, it could be both clubs who face UEFA-imposed sanctions.
Earlier today it was revealed that the European organisational body for football had opened disciplinary proceedings against Galatasaray and Arsenal, even though it was the former who were directly responsible for the large number of flares lit, it was the latter who were "insufficient" in dealing with the matter.
The flare at Tottenham was an isolated incident and not as excessive to the amount of disruption caused at the Emirates Stadium last night, however, in the eyes of UEFA's disciplinary body, Spurs may be held accountable for not properly searching match-going fans.
