Martin Jol told Arsenal fans on Thursday it was no longer realistic for them to expect a regular diet of trophies as he looked to add to their "frustration" ahead of Fulham's trip to the Emirates Stadium.
Cottagers boss Jol, who spent three years in charge of the Gunners' arch-rivals Tottenham, suggested Arsene Wenger's men were not competing on a level playing field with Manchester United, Manchester City and Chelsea after seven years without silverware.
Jol said: "If you look at the likes of Man City with almost half a billion spent, Man United, it's not easy nowadays. Can you expect a team like Arsenal to win things, with Chelsea, Man City, Man United, all these clubs?"
Asked if supporter anger was justified, Jol said: "I don't think you have to be angry. Frustrated is probably the better word.
"Angry with Wenger? Wenger created the new Arsenal, almost.
"Maybe in three years' time, they will hope and pray to get someone like Wenger."
Jol famously clashed with the Frenchman while in charge at White Hart Lane and added: "I'm not an Arsenal fan - as you well know - but I always admired Wenger for what he did.
"There is not one other team in the top four doing the same thing with the same philosophy. They always manage to find the players who are younger and create value on the pitch.
"Of course, it's probably not what an Arsenal fan wants.
"Seven years? That's a long time."
