Michael Schumacher's manager has given a rare update on the Formula One legend's condition, saying he will hopefully "one day be back with us".
Very little is known of the German's health after he sustained severe head injuries in a skiing accident in December 2013 in the Alpine resort of Meribel.
At the opening of an exhibition in Marburg, Germany, his manager Sabine Kehm said it was important to remind people of the seven-time world champion's achievements.
"He is the most successful driver in history and sometimes, on days like this, it is good to be reminded of it. 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. Racing was his life and no one would have liked to have been here more than him."
Schumacher, who spent six months in an induced coma following the crash, has been receiving specialist medical care at home on the shores of Lake Geneva since September 2014.
About two weeks ago, Luca di Montezemolo, the former Ferrari president, said the 47-year-old's health was "not good".
"I have news and unfortunately it is not good," Mr Di Montezemolo told reporters, refusing to elaborate. "Life is strange. He was a fantastic driver and only had one accident with Ferrari in 1999," he said, referring to an accident during the British Grand Prix in which Schumacher broke his leg.
Ever since the skiing accident happened, there has been much speculation about Schumacher's condition, with many reports being rebutted by Ms Kehm.
She accused Bunte magazine of raising "false hopes" shortly before Christmas when it claimed the Formula One star was walking again.
According to earlier reports he is paralysed and confined to a wheelchair, has memory problems and cannot speak. Nearly two years after the accident, FIA President and close friend Jean Todt said Schumacher was "still fighting" in his recovery.
