Lol I still can't believe this is still up for debate.
United are one of the few top clubs built by tradition and held in high esteem because of this.
Suarez (to me) stands for everything that's wrong with modern footballers.
Lies, cheats, stamps, elbows, bites, dives - repeatedly! It's not like he did it once and atoned for his actions.
Honestly for me, the worst thing he did was racially abuse Evra, considering the things he said, then to continue to deny it happened and not even properly apologise. As a person he's lower than scum to me.
And to the people who say "thats old news", "its been dealt with" etc I'm going to assume you've never been racially abused before so you're not aware of the impact it has on you as a person. It's something that sticks with you and you will never forget it. To put it into context - Balotelli was reduced to tears after he was racially abused while playing football because it has a large emotional affect on you.
Suarez could score 100 goals a season, and I wouldn't care to have him here.
For me, supporting Manchester United means more than football and winning trophies.
