Arsenal manager Arsene Wenger is determined to overcome the "gross injustice" of a 12-match touchline ban for pushing match official Paul Taylor.
The Gunners vice-chairman David Dein, also FA vice-chairman, insists Wenger is innocent of the offence.
Wenger is due before an FA disciplinary panel tomorrow for the start of a two-day appeal.
Dein said: "We have already made it very public how we feel about this and everyone knows we feel Arsene has been the victim of a gross injustice which we are determined to fight.
"That's why at the time of the ban we fought so hard to win our appeal and get a re-hearing which is the stage we're now at. The fact that we have been allowed to call new evidence is encouraging.
"But I don't want to prejudice the outcome and, although I know Arsenal fans will be worried about the case, we will all have a much better idea where we stand on Friday afternoon."
At the hearing Thierry Henry, Robert Pires and David Seaman will take the stand for the first time to defend their coach's claims that he only pushed Taylor because he was trying to prevent an argument between Sunderland player Darren Williams and Henry escalating.
