Alessio Dionisi's Sassuolo have made history after Sunday's win against Inter Milan.
Not since Fiorentina in 1955-56 has a team in Serie A won away to Juventus, AC Milan and Inter in the same season.
Their 2-0 victory at San Siro against Inter Milan was sealed by goals from Giacomo Raspadori and Gianluca Scamacca.
They had already conquered the Stadio Giuseppe Meazza earlier this term, leaving with a 3-1 result against AC Milan on November 28.
Sassuolo also won at Juventus in October.
