Concerns over the ticketing system were raised post-match after groups of Galatasaray fans were spotted gathering together from areas of the home section. United have now launched an investigation into the matter after more than 1,000 away-supporting fans managed to get hands on tickets. Large groups were seen celebrating their side's win in the Sir Alex Ferguson stand and in the upper tier of the Scoreboard End. Initial indications suggest that UK-based Galatasaray supporters bought the tickets through official club channels or via ticket touts.
