Ibra is struggling to be fit for tonight's Champions League tie against his former club.
But he told FIFA's website: "First of all, we played 4-4-2 at Inter and here the formation is 4-3-3. There's also a big difference in terms of the two clubs' mentalities.
"Here I'm playing up front as a No 9, but the Coach gives me the freedom to drift wide left or wide right, as long as I get one of the wingers to fill in for me.
"At Inter I was more isolated, so there was more space for me to move around the attack.
"The main difference is that Guardiola is more active, by which I mean when he explains something on the training pitch he can physically demonstrate what he's looking for, because he was a top-class player.
"Mourinho never played at such a high level, but both have a great attitude and a huge desire for success. They're both able to explain very clearly what they want and are direct when dealing with players.
"They are both winners."
