Michael Schumacher may never fully recover from his tragic skiing accident in 2013, his brother Ralf

Ralf Schumacher has hinted that his brother Michael may never fully recover from the mysterious skiing accident the F1 legend suffered 10 years ago after admitting that 'nothing is like it used to be' despite high-tech medical treatment.

The seven-time Formula One champion suffered massive head injuries while skiing in the French resort of Meribel on December 29, 2013.

Schumacher, who wore a helmet, was put into an artificial coma and underwent several surgeries.

His family has rigorously suppressed information regarding his condition ever since.

But now his brother Ralf has admitted that 'things aren't as they used to be.'

'Michael was very lucky throughout his life. But then there was this tragic accident.'

The 48-year-old entrepreneur and pundit added: 'Fortunately, advanced medical science provides many opportunities. However, nothing is like it used to be.'

Ralf, who won six F1 Grand Prix, emphasised that Michael had been more than just his older brother.

He told local media: 'Michael wasn't only my brother. When we were kids, he was also my coach and mentor. He taught me literally everything about kart racing.'

Ralf said: 'There may be an age gap of seven years, but he was always by my side. We raced together, we practised overtaking manoeuvres and everything that matters in motorsports.'

The former Jordan and Williams driver underlined: 'He passed on all the different things he had already internalised. I had the honour to learn from the best.'

Reflecting on how the Schumachers have dealt with Michael's devastating skiing crash, Ralf said: 'It has been a significant experience for me but, of course, even more so for his children.'

Ralf concluded: 'Life is unfair at times. That day held a lot of bad luck. This fate has changed our family.'

Ralf was married to former model and television presenter Cora Schumacher for 14 years. They divorced in February 2015.

Their 22-year-old son David competes in the Deutsche Tourenwagen Masters (DTM) racing series.
