Both scored hat-tricks in victory over Atalanta.
"Ever is a quality player, and he knows how to find the spaces for us to be effective," Pioli said in his Press conference ahead of the Torino game.
“He's done well to work with openness and willingness. Not just him, we want everyone to be determined for the next game.
“I never explain my choices, the players know that I choose what's best for the team. They're all fit and they're willing and available, that gives me choices but at the same time makes it harder to choose."
He added: “Icardi is very strong. Belotti is very good but Mauro has the ability to the Capocannoniere. He's very important for us, we expect a lot of goals from him but he's always decisive and he works for the team."
