Giroud missed Milan‘s last two games will back pain, but he will be available tomorrow when the Rossoneri travel to Spezia.
It kicks off at 14.00 UK time at the Stadio Alberto Picco.
“Giroud will be called up and he will play, but we need to decide whether he will start or come on as a substitute,” Pioli said at a press conference.
“Calabria will be available tomorrow. Since the beginning of the season, we’ve only had two muscular injuries, Kessié and Krunic. All the others suffered muscle fatigue.
“Florenzi will not be available because of a knock to his knee,” Pioli explained.
“He could not train this morning, so I hope he can be ready on Tuesday. He is not yet 100 per cent, but he is a smart player, I count on him a lot. I hope he will soon reach his peak,” the coach continued.
“Messias arrived with a few problems and he is overcoming them. It’s a pity that not all the players are available, but I have a strong team.”
The Rossoneri have collected 13 points from the opening five games of the season and sit just two points behind table leaders Napoli.
“I expected this Napoli, they haven’t changed much and they added Anguissa who is strong and I’ve known for a long time. They have depth and are among the candidates for the title,” Pioli ensured.
“There will be a lot of competition for the top four. I’m happy with my team, I have quality and many options.
“Together with the fans, we have more energy and enthusiasm. We started well at home, but we are only at the beginning. Tomorrow we play away against a team to be respected.
“It’s an important game, the starters will play a key role, but the same goes for those who come on from the bench.
“All those who played on Wednesday are promoted. When everyone’s fit, my choices are just technical. Tomorrow I will pick the best line-up depending on what I see during today’s training,” the coach continued.
The Rossoneri suffered a shock 3-0 defeat in the same fixture last season, so Pioli expects something different tomorrow.
“We lacked everything against Spezia last season. This time, we must not concede as much and be more dangerous. We need clear ideas. We need to use different solutions and press high up the pitch, then we’ll see what game they will play.”
The Rossoneri will then host Atletico Madrid at San Siro in the Champions League on Tuesday September 28.
The Serie A giants had played their last home Champions League clash against the Colchoneros in 2014 with Clarence Seedorf in the dug-out.
