Two Leeds United fans were stabbed to death during a UEFA Cup game against Galatasaray in 2000 . Many Manchester United fans paid their respects , leaving tributes at Elland Road , and there were even reports of Leeds and Manchester United fans embracing , with '' The Independent '' using the headline " Old rivalries forgotten as fans unite in grief " . However , by the time the two sides faced up in the league , a subsection of Manchester United fans unfurled banners bearing the words " '' MUFC Istanbul Reds '' " and " '' Galatasaray Reds '' " , glorifying the killers and mocking the victims . The Manchester United fans who unfurled these banners may have been retaliating to consistent taunting by Leeds fans about the Munich air disaster over the years ( these chants have also been made by the supporters of many other clubs , particularly Liverpool ) , but these banners angered the Leeds fans , who retorted by chanting songs about Munich , and there were reports of seats being ripped up and confrontations after the game
