Arsenal managing director Danny Fiszman isn't concerns after Alisher Usmanov increased his stake to 23 per cent yesterday.
Russian metals billionaire Usmanov claims he can employ a blocking vote if he obtains 25 per cent.
But Fiszman, now living in Geneva, has told an Arsenal fans group that they will fail.
He said: "No hostile takeover bid will be successful.
"It's nonsense Usmanov can get a blocking vote. Owning 25 per cent will only allow you to block special resolutions.
"In 16 years, Arsenal have had two special resolutions, the Emirates and the shares issue with Granada TV.
"His shareholding will not affect the running of Arsenal in any way."
