Ashely Cole's agent Jonathan Barnett has vowed to clear both their names after Cole's £100,000 fine for the Chelsea tapping up row.
Cole was punished by the Premier League for his meeting with Blues' chiefs in a London restaurant in January.
"We are not prepared to accept what has happened and we will do what it takes to clear our names," said Barnett.
"We feel so strongly about this we will appeal and fight on. We will not stop. It would be easy to accept the fine."
He added: "This is the most important thing in our lives at the moment.
"I am actually more determined to clear Ashley's name than my own. But I have always maintained that I am innocent of any wrongdoing."
Cole was found guilty of approaching Chelsea when the Premier League's independent commission gave their verdicts in the tapping-up row on Wednesday.
While the Arsenal full-back's conduct was deemed to have been "unacceptable", the commission ruled that he had been "manipulated to a large extent by his agent".
The FA have started gathering evidence on Barnett's alleged role in the affair, with a misconduct charge possible in the future.
