#1: A guaranteed return to the top

A study of the Italian's managerial history reveals the fact that he hasn't stayed at a club for more than two years since his nine-year spell at the San Siro. Despite the relatively short spells at Chelsea, PSG, Real Madrid and Bayern Munich, the Italian has never failed to deliver, winning 11 trophies in eight years since leaving AC Milan. He has won the league title in all the four countries, including England.
If Ancelotti's is shown the same amount of patience gifted to Wenger, the 58-year-old manager will definitely return the Gunners to the pinnacle. Also, with the pressure being considerably less at the Emirates, the former Real Madrid manager might perform better, bringing stability to the club.
You decide, should they still persist with Wenger when Ancelotti is out there, as a free agent?
