The talented winger has also shone bright at Euro 2020, helping Italy advance to the competition's semi-finals.
Sassuolo understand that it will be difficult to hold on to the Italy international ahead of this coming season.
But the Serie A outfit hope to maintain Berardi, whom they describe as their "symbol".
Sassuolo chief executive Giovanni Carnevali told Radio 24: "Berardi is our symbol, we have a deep bond with him.
"He is doing extraordinary things. He has shown his values and the decisions over the years where he gave up on big clubs were not bad choices.
"We hope to keep him. It is not easy to do, even with him."
