I seriously doubt whether either set of fans can refrain from hurling abuse at each other during the tribute to the 96. Add to this the suarez / evra handshake situation and you have the potential for serious problems today. I think most united fans will observe it , but all it takes is one person to break it and all hell will break loose. I was at goodison on Monday and was relieved the club chose not to play you'll never walk alone as just one idiot is all it takes to disrespect and the rest are blamed also.
