Iturbe has a pretty high offensive workrate, i dont see how he would be less effective. In fact, from the team pov, he is actually better suited to conte's tactics.
Why ? Because some players need some tactical guidance. Example : hazard need those or he will come toward the ball every time, and clog the play.
Same with Iturbe. He works hard, well in conte's system those characteristics would be used to their strenght, added with the obvious general guidelines.
