Arsenal fans may boycott their Champions League tie with Bayern Munich next week over ticket prices.
The Daily Mail says season-ticket holders must pay between £62 and £132 to attend the first leg of the last-16 showdown.
And that has put off supporters whose season tickets do not cover the Bayern game.
Arsenal Supporters' Trust spokesman Tim Payton said: "We are very concerned. Season-ticket holders have already paid up to £2,000 in advance - the highest in world football. Their commitment deserves better. Arsenal's grasping approach will have a detrimental effect on the noise in the ground, harming the team's chances for an important game.
"Ivan Gazidis (Arsenal's chief executive) promised that when commercial revenues rose it would reduce ticket price increases. To date, those are just empty words."
