It'll be the first time Pioli has faced Inter without the Swede.
"We must also take into account the characteristics of the opponents. It is important. We will never distort our way of playing and tomorrow makes no exception," Pioli said at a press conference.
“We are fighting up there. Whether it's for the title or the Champions League, we are competitive again. We played a great game against Juventus, but we lacked quality in the final third. That's what we need tomorrow. It's a crucial game and we want to win it.
“Neither Zlatan [Ibrahimovic] nor Ante [Rebic] will be available, Tomori made great work and I think he will be with the team, although he may not start. Olivier Giroud is an important player and he is ready.
“We are sorry that Ibra won't be there. We've improved a lot thanks to him, but now we must prove to be strong also without him. We must have the strength of will, especially in tough moments."
On Inter, Pioli said: “They are doing something extraordinary, but I know we have a strong and united team, with motivated players," the Rossoneri coach said.
“There will be many duels and the team that wins the most of them will have more chances. We must be more motivated than them. It's an important game for so many reasons."
