Olympique Lyon president Jean Michel Aulas is pushing to sign Chelsea defender Kurt Zouma this week.
Aulas, reports L'Equipe, has flown to London to meet with Chelsea officials for the Frenchman.
The OL supremo touched down in London yesterday and went straight into a summit with Chelsea representatives about a deal for Zouma.
Nice have also expressed interest in the stopper, who is likely to leave on-loan this summer.
Zouma fought back from long-term injury last season, but struggled to break into manager Antonio Conte's plans over the second-half of the campaign.
