Manchester United have sent a letter to supporters to remind them their safety will be at risk if they wear club colours for the Europa League game away to Zorya Luhansk amid fears of further violence.
The club told fans travelling for the game in the Ukrainian city of Odessa on Dec. 8 to avoid drawing attention to themselves as "due to political sensitivity in the region it is not just opposition football fans who may potentially pose a risk to your safety."
Fenerbahce fans and Feyenoord supporters were reportedly attacked during their group-stage matches, and United, who had issued advice warning of the dangers of the trip when making tickets available in September, have now sent out a reminder to those attending the game.
