Both sets of players had left the field of play before the fighting broke out.The Yorkshire Post have reported that a group of Frankfurt supporters were held outside the 2000-capacity Sportzentrum in Eugendorf before the match but were allowed to enter at kick-off.The newspaper quoted Neil Slinn, a Leeds fan at the match, as saying: “A few of us went over to applaud the Frankfurt fans."I was going to shake their hands. Then their ultras jumped over the (advertising) boards and started attacking us."Some were wearing balaclavas and we were outnumbered.”
