It seems ambitious that either Liverpool or Tottenham would pay the price.
Domenico Berardi (L) celebrates with Sime Vrsaljko
Sassuolo chief Giovani Carnevali has said that attacker Domenico Berardi can leave the club this summer, at a high price.
Berardi rose to prominence as a teenager, netting four goals in one game against AC Milan, but has found goals tougher to come by since.
The Evening Standard linked Italian international Berardi with a £26 million move to Tottenham Hotspur a year ago - now Sassuolo want an even higher price.
Carnevali told Radio Rai, report Calciomercato: "Berardi has had a difficult season because of injuries but he’s recovering well.
"We hope he can become a legend of Sassuolo but if any club want to sign him they will be required to match his price-tag. Forty million? That could be an adequate sum.”
Domenico Berardi scores for Italy from the penalty spot
The 40 million Euros Sassuolo want works out at £35 million, and is a steep fee for Berardi given his goal return this season.
He has played in 13 Serie A games, scoring twice, and providing four assists. His figures look a bit better taking into account he scored five goals in four Europa League games.
For Tottenham or Liverpool he would be a smart acquisition, as a player who can play on the wing or up front, and has a knack of netting in big games.
But at the fee Sassuolo are demanding, both clubs would be better off focusing their efforts elsewhere, perhaps on Fiorentina ace Domenico Bernardeschi, 23, who has netted 13 goals from the wing this season.
