Benitez won the league 2ce with an unfancied team like Valencia with half the resources of the duopoly. He also won the UEFA cup with them. So he too will be idolised at that club.
Benitez won the CL and reached the final again in 2007. He again won the Europa cup and with Inter won the Club world cup.
Wenger has never won a European cup of any type. Has never managed any of the big teams (We arent really in the top 10 in Europe) and went 9 years without winning diddly squat.
So in the real world Rafa rules over Wenger.
