For the second time this summer, Arsenal shareholder Alisher Usmanov has blasted the north London club, claiming "the current politics of the club's management" are a major factor behind their trophyless run.
Usmanov, whose Red and White Holding company has a 29 per cent stake in Arsenal, last month sent a strongly worded letter to the club's board accusing them of a lack of investment following Robin van Persie's decision not to sign a new contract at Emirates Stadium.
And the Uzbek billionaire, who is the Gunners' second largest shareholder after Stan Kroenke, but does not have a place on the board, has again called for changes to be made behind the scenes.
"Disregarding the series of trophyless seasons, you have to accept that a few of the current board of directors were at the helm during the greatest moments of the Arsene Wenger era," Usmanov told Forbes Magazine Russia.
"But the footballing landscape has changed. Our point of view on which direction the club is going today, and our disagreement with this direction, have been laid out in our open letter to the board.
"We do not consider just qualifying for the Champions League to be the chief ambition of the club, and with all our hearts we support the team and wish them well for the new season.
"Victory is absolutely not ruled out, but the current politics of the club's management will leave Arsene Wenger and his team with fewer and fewer opportunities in the long run."
However, he insisted that despite his issues with the club, he has no plans to sell his stake.
"We plan to continue to buy shares in the club," Usmanov added.
"From the point of view of investment, this has already been a successful policy: the value of the club has rise from £300-400 million to £700-800m.
"But this is not the point. I am a fan and I am not going to sell these shares at any time, since this is the club that I consider the best in the world."
