Atalanta midfielder Mario Pasalic admits he enjoyed preseason at Chelsea under Maurizio Sarri.
Pasalic is on-loan with Atalanta this season.
He said of his parent club, "I watch them every now and then. In a week with them training in Australia, I got to breathe in the Sarri style of football: quality and aggression, possession and pressing, all combined beautifully.
“I don't regret leaving, because what good would it have done me to sit on the bench? I don't belong at Chelsea right now, or at any top club, because I still need to figure out if I can reach that level. I can't do that without playing regularly for two or three years.
“I might return to Chelsea, I might realise that Atalanta is my big club, but either way I don't want to make the wrong decision."
