Lille have appointed Bruno Genesio (57) as their new head coach, with Paulo Fonseca (51) departing after two years in charge, the Ligue 1 club said on Wednesday.
Media reports have linked Fonseca with a potential move to Serie A side AC Milan.
Genesio was a midfielder at Lyon for a decade and later coached them for four years. His last managerial role was at Rennes, where he spent two years.
"It was a no-brainer for us when Paulo left, so much so that Bruno was the only coach we contacted and spoke to," Lille president Olivier Letang said in a statement.
"Bruno has a wealth of experience in football, both in Ligue 1 and in European competitions."
