Lazio have confirmed Stefan De Vrij “will undergo his medical tomorrow morning” after a deal with Feyenoord.
Dutch and Italian media had already suggested terms had been agreed and it was made official on Lazio Style Radio.
“Stefan De Vrij will arrive tonight at Fiumicino airport and tomorrow morning at 8am will undergo his medical at the Paideia clinic,” announced director of communications Stefano De Martino.
“We welcome with joy the best defender at the World Cup. He is an international-level signing.”
The deal is believed to be worth €9m and the Biancocelesti won out despite interest from Manchester United.
