Dennis Praet has left Sampdoria for Leicester City in a move reported to be worth £18million (€19.5m).
Belgium international midfielder Praet signed a five-year contract at the King Power Stadium.
The 25-year-old established himself as a star performer in three seasons at Samp and was said to be the subject of interest from Juventus last year.
Praet subsequently signed a new contract that ran until 2021, but he has now moved to the Premier League.
He joins a midfield that already includes the talents of compatriot Youri Tielemans, Wilfred Ndidi, James Maddison and Hamza Choudhury.
