The former midfielder says today's Gunners roster does not have the same range of good players as the squads he was a part of through the 1990s and early 2000s, which could explain the reason why Arsenal have not won a trophy in six years.
"When his major players get injured there is not enough quality behind who can come in and do a job," he told talkSPORT.
"When I was playing, when vital players got injured like Dennis Bergkamp, we still had players who could come in and do a good job. That's the difference now.
"If Arsenal get their top side out they are a very good side, there's no doubting that.
"But if a couple of them get injured, have they got enough back-up?
"Players like Bendtner and Denilson, can they come in and do a sound job? Last season they had their chances but I don't think they did."
