Manchester United fans are fuming that hundreds of Galatasaray supporters watched Tuesday night's Champions League game in 'home' sections of the stadium and that a huge banner celebrating the history of the club was ripped down.
There were huge cheers loudly from followers of the Turkish club when a sign reading 'There is nothing on earth like being a Red' was ripped from the second tier of the East Stand.
It capped a problematic night at Old Trafford with large numbers of Galatasaray fans dotted throughout the stadium in addition to the official away end where they have been allocated nearly two thousand tickets.
