Locatelli, 23, was part of the Italy squad that won Euro 2020 last month, scoring twice in five games and coming on as a late substitute in the final. The deal will become a permanent transfer in June 2023 for a further three years, with a fee of up to 37.5m euros agreed. Locatelli joined Sassuolo in 2018. The former AC Milan player had been linked with both Arsenal and Liverpool during this summer’s transfer window. Juventus missed out on the Serie A title for the first time since 2012 as they finished fourth last season and reappointed former boss Massimiliano Allegri in May after sacking Andrea Pirlo. They begin their 2021-22 Serie A season at Udinese on Sunday. Juventus forward Cristiano Ronaldo on Tuesday criticised media reports linking him with a move away from the Turin club.
