this whole damned thread is subjective. stop thinking that only your own thoughts are "FACT".
basically it just comes down to what YOU believe to be important for someone to prove that they are a great manager. Some people value results, some, style, some people even value the underdog manager for example tony pulis who manages shit teams but does well in them - can you say the great managers can do the same? its all subjective.
facts are; pep's teams have won lots and play with swagger - also, a lot of money has been spent to get the players he wants who he believes he can play his style (not many managers get to work with their target players)... sooo he does well with what hes got.
in reality (on average) (according to soccernomics - a great read into football) there are two things relevant here:
a)managers on average affect team's success by up to 5%
b)the thing that most affects and correlates with success in football is player wages.
This thread might piss some people but that's what I believe. He's a good one but no where near the level he is rated. One of the most overrated coach.
