Former Barcelona defender Eric Abidal has sung the praises of Lyon defender Samuel Umtiti.
Umtiti has been linked with Barcelona, while Tottenham boss Mauricio Pochettino admitted his interest this week.
Abidal stated: "He is world class. That's why he started at a club like OL.
"He has many qualities.
"I truly wish him the very best for the coming years. He is such an important player that it would be very tough for OL to release him."
