Arsenal fans are upset with plans to raise season ticket prices for next season.
The London Evening Standard says the Arsenal Supporters' Trust have written to the club spelling out their opposition and will put their fears directly to chief executive Ivan Gazidis on June 13, when he will attend a meeting with their members.
And another fans' group are organising a walk ahead of Arsenal's final home game of the season to highlight their concerns that the club are becoming "a faceless corporate monster".
The AST - the most influential of the club's supporters' groups with around 1000 paying members - are worried that ticket prices, which are already the most expensive in the country at £893 for the cheapest season-ticket, could increase by as much as 6.5 per cent.
That was the price rise agreed for 7,000 executive Club Level tickets, and the fear is that regular supporters, who have just seen the club's season hit the rocks, will also be hit in the pocket.
