"I don't think there's that much difference between playing well in Italy and in Europe," Pioli said.
"The Champions League does require a higher tempo, but nothing impossible. I understand there are expectations around the Chelsea games, but I maintain the most difficult match for us will certainly be against Empoli.
"When we go into that fixture, I'll have welcomed the players back from international duty only two days earlier. I trust that if we play at our usual levels, then results against Chelsea are certainly within our reach."
