The Arsenal Supporters' Trust has called for a youth injection to the club's board.
The Gunners are heading for an eighth trophyless season after last weekend's shock FA Cup loss at home to Blackburn and Tuesday's Champions League first-leg defeat against Bayern Munich.
"The board need to consider recruiting new members who can support and challenge Wenger to be a better manager.
"It's wrong to focus on just him. Every single non-executive director of the club is over 70 years old and it is time for some fresh blood.
"We would call for [majority shareholder] Stan Kroenke to meet with [second-largest shareholder] Alisher Usmanov to work out how to make it stronger."
