Lyon coach Bruno Genesio says the club is proud of Samuel Umtiti's success at Barcelona.
Since leaving OL two years ago, Umtiti has emerged as one of the world's best defenders and become a World Cup winner.
Ahead of their Champions League clash with Barca, Genesio said: "We are all proud because he is happy with his evolution.
"We knew his potential and we knew he could reach a very high level, and he demonstrates it with one of the biggest clubs in the world, where he won a star and the recognition of the public of Barcelona."
