Leicester have completed the signing of Wesley Fofana from Saint-Etienne for a fee of £30m.
Fofana broke into the Saint-Etienne first team last season and went on to make 14 appearances in Ligue 1.
Usually deployed as a central defender, he can also play right-back.
He says the high-level of player and manager at the club convinced him to come.
"I’m very happy to be here," Fofana told the official club website.
"I’ve watched Leicester City closely since they won the title and they’re a top club in the Premier League. I know I will learn a lot from the players and the manager here, which is one of the main reasons I came.
"I can’t wait to get started.”
Fofana is Leicester's third signing of the current transfer window, having already recruited Timothy Castagne from Atalanta and Cengiz Under on loan from Roma.
Following the disappointing end to last season which saw the Foxes miss out on Champions League qualification on the final day, they have made a superb start to the 2020/21 campaign and are one of just three teams alongside Liverpool and Everton to have won their opening three fixtures.
Saint-Etienne released a statement this week confirming the sale, and that they agreed to it due to the financial boost they would receive during the current coronavirus crisis.
"The decision to sell the player was taken collegially by the management board and the shareholders," the statement said.
"ASSE accepted Leicester's exceptional offer, especially given the uncertain economic context caused by the health crisis."
