' LAST NIGHT '
Riot police were ordered into position in front of Galatasaray fans after flares were hurled on to the Emirates Stadium pitch in the first half of Wednesday night's Champions League tie against Arsenal.
Several flares were thrown on after defender Felipe Melo had put in a two-footed lunge on Alexis Sanchez in the 36th minute.
The Gunners led 2-0 at the time following two goals from Danny Welbeck.
And the clubs could face sanctions as a result, with UEFA confirming it may take action after considering the report of its match delegate.
