You mean apart from the 3 times he has won the PL and this time is second behind a very good team, or perhaps the La Liga he won or the 2 Premeira Ligas he won. Yeah, apart from that he is just a knockout manager.
2002/3 Primeira Liga: Sporting were absolute ****e that season, making the league 50% easier to win given the dreck in the rest of the league
2003/4 Primeira Liga: Sporting and Benfica both turned up, meaning a whole four games were important that season
2004/5 Premier league: Man Utd had a transitional season, thus removing 50% of the challenge - and the other 50% was Arsenal
2005/6 Premier League: Arsenal were ****e that season, thus removing 50% of the challenge
2008/9 Serie A: Juve were rebuilding post-Calciopoli while Milan's team was ageing rapidly
2009/10 Serie A: Juve were so bad they barely qualified for the Europa League while Milan were rebuilding, making it a cakewalk
2011/12 La Liga: Barca were the only threat so that's a whole two league games he needed to win
2014/15 Premier League: Man Utd, Man City and Arsenal all had stuttering seasons while Liverpool were barely qualified for the Europa League
Have you noticed the pattern there? His "success" is built on two things: leagues where there's barely any actual competition and the usual title challengers having off seasons - which by complete coincidence allows him to set his teams up like they're playing in a cu[p competition, usually aiming for a home win and away draw against those sides. Yet when the other title challengers
do turn up, by complete coincidence he's not the one with the league trophy in his mitts at the end of the season.
As for this season's "success" let's put it into context, shall we?
* Spurs had a slow start to the season, coupled with a couple of derp periods in November and April
* Saltypool had a slow start to the season as their team hadn't gelled and their crap defence was exposed, coupled with resting players late in the season
* Chelsea have been an utter trainwreck all season
* Arsenal had graciously removed themselves from the equation
So this season there were just two games Steptonho needed to focus on as the other contenders were cancelling themselves out just like what happened in 2014/15, but his tactical quote-unquote masterplan failed to take advantage and he was left with nothing other than some tetchy press conferences and at least a dozen players he attempts to shift the blame onto for his own failures.
