Michael Schumacher's manager has called for "support and patience" in the hope that one day the seven-time world champion will return to health.
Schumacher suffered severe head injuries in a skiing accident in December 2013 and is still in recovery at his home in Switzerland. Details of his condition remain scarce, but speaking at the opening of an exhibition to celebrate his career, his manager Sabine Kehm said there is still hope that one day he will be "back with us".
"He is the most successful driver in history and sometimes, on days like this, it is good to be reminded of it," Kehm said.
"Of course, Michael is not here and of course we miss him. We know what has happened and cannot change it. We must accept it and hope with everything we have that, with continued support and patience, he will one day be back with us."
Earlier this month, former Ferrari boss Luca di Montezemolo said the news was not good on Schumacher after saying he regularly checks up on the condition of the seven-time world champion.
