Mancini's squad was so much stronger than the rest, winning the title year after year was only normal. It's like with Lyon a few years back when they became champions seven years in a row. But in the CL, Mancini's Inter was very poor and never managed to get past the second round of the competition. (I'm purely trying to explain Mancini's situation in Italy) I do think people are being unfair towards Guardiola. Yes he has a absolutely fantastic squad and yes that plays a huge part in his succes but like Henrique said, it was pretty much the same squad that went through a rough patch for two seasons. You have to give the man credit for things like getting rid of the likes of Ronaldinho and Deco (though the Eto'o + money - Ibrahimovic swap was a huge mistake), spotting Busquets' talent very early when many criticized him for benching Touré, Valdes growing out into a fantastic goalkeeper under him after being average GK for years, giving Messi a new role as a false number 9 which helped him become an even better player than he already was and some more good/great decisions.
