Just tell me this, is Ranieri one of the greatest coaches of all time then?
Rainieri name turn out time to time by Man City fan when we are arguing about winning the title with lower ranked team. This is not a comparison at all, comparison must be apple to apple. But I do agree Ranieri was 10 times better than Pep that season.
First, we can not make Pep managed a lower ranked team nowadays, he next destination would be PSG, no one else can afford him and giving him big money to spend like Man City.
He has spend more than 900 million net in 5 or 6 seasons, if you need a coach could bring you success with money spent you go for him ( without CL title I mind you ).
If you prefer to spend low, 100 million net in 4-5 seasons and also bring you some trophies ( including CL) you can go for Klopp, Net spending just more than 100 million in his time at Liverpool ( 2 biggest signing money are generated by selling that Brazilian midfielder to Barcelona x 10 times of his value )
If you have no budget, and still hope for one season wonder, you can go for Rainieri.
If you want a coach who bring you positive net spending, you bring back Wenger.
They all have different resources, you can not judge who is better.
Ask SAF first before you say Pep is the all time greatest coach.
