He told Sky News: "Fabrice is critically ill. The next 24 hours are going to be absolutely crucial.
"We've obviously been inundated with people wishing him well and we hope that if everybody can pray strongly tonight that Fabrice is able to recover.
"It's very serious. There's no getting away from that. He's critically ill and God willing he makes it through."
