“Lazio have acquired the rights of player Mohamed Fares from SPAL,” the club said in a statement.
The transfer is reported to be worth in the region of eight million euros ($9.3 million).
The 24-year-old French-born player played for five seasons with Hellas Verona before joining SPAL in 2018.
He suffered a knee injury last year and was sidelined for several months. SPAL were relegated from Serie A last season.
