The Gunners are currently battling for Champions League qualification with the side fifth in the table, two points behind Tottenham but with a game in hand.
Wenger's side are 21 points off Premier League leaders Manchester United, which has led to criticism over the quality of Arsenal's strength in depth.
The Frenchman has subsequently come under pressure to spend in the summer, and, amid suggestions he has £70 million at his disposal, Dein is sure his former colleague will bolster sufficiently.
"Clearly they have fallen 20-odd points behind Manchester United which is not good enough and it speaks for itself that he has to strengthen the team and I know he will do that," Dein, who left Arsenal in 2007, told BBC Radio Five Live.
Of Wenger, with whom Dein enjoyed a close working relationship, he added: "I think he has the fire in his belly. I don't see any reason why he shouldn't be there.
"He is one of the best managers in the world, he has been coaching for 30 years, he knows what he is doing, he knows what he wants and I think it's just a question of identifying the right talent."
