Think of Michael Schumacher and you immediately link him to the sport of Formula 1, in the same way which Michael Jordan will forever be remembered in basketball circles.
For Sebastian Vettel, Schumacher is a person who he has always looked up to, and still remembers the important advice the seven-time world champion passed on to him early in his career.
The health status of Schumacher has been an ongoing mystery after a skiing incident in the French Alps in December 2013, where he hit his head on a rock.
It was reported at the time that he suffered a number of blood clots on the brain from the impact of the crash.
Statements from the family over his current condition have been extremely rare and they are adamant that they will be respecting his privacy above all else.
The Express reported Vettel as saying: "I've seen the tribute show for Michael Schumacher. I got goose bumps and my eyes welled up.
"Michael was my childhood idol and will always be my idol.
“I miss his advice, it was perfect. It could be adapted to any situation, and it would work.”
"He will always be the number one."
Vettel then reminisced about the first time he actually met Schumacher, and the German admitted that he was simply starstruck.
"I remember when I met him for the first time, I could not open my mouth, I was so tense.
"Over time I got to know the person who is not just a race driver, he's been working hard to bring Ferrari to the top. Incredible.
"He is one of the few people you meet in life, who have an answer for everything."
The pair raced together on five occasions, representing Germany in the Race of Champions between 2007 and 2011.
Schumacher's record is currently the standard bearer for the sport, having won seven world championships (five with Ferrari and two with Benetton) and winner of 91 races in 306 starts.
Of the current generation of drivers, Vettel is closest to his fellow German in terms of driving championships (four), while Lewis Hamilton leads the way in terms of race wins (60 from 203 starts).
While Schumacher's immediate future is far from clear, what will go down in immortality is the impact he made in the sport and the drivers that have followed his path.
