Sevilla have completed the signing of France Under-21 international defender Joris Gnagnon from Rennes.
Gnagnon has signed a five-year contract with the La Liga side for a fee reportedly worth €15 million.
The Paris-born defender made the move to Rennes at the youth level in 2014, making his first team debut in 2016.
The next season would see Gnagnon make 27 appearances, all starts, in Ligue 1 for the Brittany club, scoring his first senior team goal in the process.
The 21-year-old added two more goals last season for Rennes, as he played in 36 league games, starting 32.
