Ferrari issued an emotional message on Thursday to mark the 50th birthday of Michael Schumacher, who has not been seen in public since he suffered head injuries in a skiing accident five years ago.
The German, who won a record seven Formula One drivers' championships and 91 Grands Prix, collected five consecutive titles with the Italian team from 2000 to 2004.
Ferrari also won six constructors' titles while Schumacher was with them.
"Our champ turns 50 today. We're all with you Michael #KeepFighting," Scuderia Ferrari tweeted.
The official Formula 1 account tweeted: "We join the whole of the #F1 family in sending Michael @Schumacher our very best wishes on his 50th birthday #KeepFightingMichael #Michael50."
