The Gunners have endured a frustrating eight years without landing a major trophy, with the last addition in their trophy cabinet coming in the form of the FA Cup in 2005.
Arsenal's lack of success has forced the club to sell several of their top players, including the likes of Cesc Fabregas, Alex Song and Robin Van Persie, in recent years, and the Gunners' failure to replace them with established names has been a source of frustration for the club's fans.
Robben believes that the reason for Arsenal's failure to win a major trophy for so long is down to their flawed transfer policy and claims they will not be able to win any trophies if they keep selling their top players.
"I think you can see it [why Arsenal cannot win trophies]," Robben told the Sun.
"It's not my opinion, it's also a fact.
"The last eight years - no trophies. That says it all.
"If you look around at the moment there are some teams in England that are maybe stronger than Arsenal.
"Again, I live in Germany, I don't live in England, so it's very difficult for me to really judge this situation at the club.
"But if you see there are always players leaving and when they leave, at that moment, they are the most important players or the best players and, if you keep losing these players, then every time you have to try to build up again."
However, Robben has backed Arsenal manager Arsene Wenger to turn things around for the club.
"Mr Wenger has shown that he can do it," Robben added.
"He's a great manager, he's shown that by improving young players, but the trophies are also important.
"You already said it. There's a difference. I can understand it - the disappointment.
"Eight years without a trophy is a very, very long time."
Robben also claimed that he understood why international compatriot Van Persie chose to leave the Gunners during the summer.
"Yes, Robin was the captain, but that's also how it goes in football," Robben mused.
"Players are leaving. In the end, of course, for the real Arsenal supporters it was a shame, it was very disappointing that he left the club.
"But on the other hand, if they think clearly, everybody understands his choice that he also wants to win titles and at Arsenal at the moment it's going to be very difficult."
Nonetheless, Robben has warned his side against underestimating the Gunners in their Champions League clash.
"People will say that we're favourites but we can expect two very tough games," Robben declared.
"I know they lost their best player in Van Persie and they got some new players in, but they're still a very dangerous team.
"They have a young team with a great manager, who always improves his teams and can develop young players.
"We won't underestimate them. Maybe they're struggling a bit but Champions League nights are always special and anything can happen.
Bayern have won the Champions League a respectable four times, while Arsenal have yet to enjoy success in the competition.
