Terry, 31, is accused of calling
He denies a racially aggravated public order offence, and claims that he was sarcastically repeating the slur that Ferdinand mistakenly thought he had used.
Cole, also 31, told Westminster Magistrates' Court: "I think we shouldn't be sitting here."
He said while racism should never be tolerated, repeating what you thought someone said was 'completely different'.
Cole said: "If I repeated something that I thought you said, that's totally different than if someone just says something."

Mr Carter-Stephenson said: "Did you want to get involved in the situation?"
Cole answered: "No."
The barrister asked: "When you made the statement what was in your mind?"

Mr Carter-Stephenson continued: "Did you feel there was any conflict?"
Cole said: "Yeah. JT is my team-mate and friend, Anton and Rio and his family, I've known for a long time."
Cole said on the day of the match at Loftus Road, he saw Ferdinand make a fist gesture to imply sex and could see him saying something.
He said: "I can't make out - him either saying Bridgey (Cole made the fist gesture) or black."

The two players then shook hands and went their separate ways.
The trial was adjourned until Thursday, when prosecution and defence counsel are expected to make their closing speeches.
