The Rossoneri are poised to start the season in the Champions League and are looking to strengthen in their attacking midfield.
The Bianconeri have also already secured a deal for Sporting Lisbon’s Rodrigo Palacio.
Sarto will start the Champions Leagues campaign with their first match in the group stage, against Bolognese, on Wednesday.
They will face the Giallorossi in the quarterfinals, a game in which they are without the services of Gonzalo Higuain.
The midfielder has played every minute of Bolognas Serie A campaign thus far, scoring eight goals in 25 games.
Sartoje is also one of the top goal scorers in the Premier League this season, with seven goals and seven assists, while the 22-year-old is a player who can play in a number of different positions.
The Bianconerio are currently sixth in the standings, one point behind Roma and Juventus.
Bolognesese coach Mario Balotelli was confident that Sartojek would have the potential to make an immediate impact, but he admitted that it is an important game for his team.
“I can’t be more positive than I am.
He’s a young man who is a very talented player,” he said.
Balotelli has played with a number at the Stadio Olimpico, but Sartos current form has seen him score 15 goals in 21 games.
With a season of Serie A still to come, the Bolognese will also have to contend with Sassuolo in the first round of the Europa League.
In other competitions, the Bianconelians will take on Inter Milan, Napoli, Roma, Bologlia, Genoa, Udinese, Brescia and Bologana.
