William Vainqueur has completed a move to Roma from Dinamo Moscow, the Serie A side have confirmed.
Rudi Garcia's side announced the capture of the 26-year-old midfielder on Monday.
The Frenchman had spent one year with the Russian club and was a first-team regular following his move from Standard Liege.
"I'm here because Roma are a great team and Rome is a wonderful city," the former Nantes player told the Italian side's official website.
"I'll give my all for this very famous shirt. I've heard a lot about the Giallorossi fans – they're one of the best sets of fans anywhere."
Vainqueur's move to Stadio Olimpico strengthens Roma's squad further following the recent arrivals of Edin Dzeko, Lucas Digne and Mohamed Salah.
