The French left-back has lodged a complaint against the Uruguayan striker following Saturday's 1-1 draw between United and Liverpool at Anfield and Ferguson says he is not about to back down despite Suarez being upset about the allegations.
"I spoke to Patrice today. He is adamant he wants to follow it on," said Ferguson.
"It is not an easy one for us.
"Saturday was terrific. Both sets of fans were good. There was not any of that silly chanting we have had in previous years. Both sets of fans deserve praise for that.
"Obviously Patrice feels very aggrieved at what was said to him.
"It rests in the hands of the FA now."
