Suarez has admitted to saying it once, Evra accused him of saying it 10 times in a interview.
If the papers are to be believed Evra in his written statement has only now accused him of saying it once.
The thing you are missing is all of this was spoken in Spanish and Evra said "Dijo desaparecen Sudaca" With Sudaca being highly offensive to someone from a south american country, This is why LFC in there statement have said "We would also like to know when the FA intend to charge Patrice Evra with making abusive remarks to an opponent after he admitted himself in his evidence to insulting Luis Suarez in Spanish in the most objectionable of terms."
I'm not defending him using the word i'm defending him from people calling him a Racist when he clearly is not. Also for people to actually look at the real meaning of the words spoken.
