Jenson Button has recently released his autobiography book - "Life to the Limit".
In a certain extract of the book, Button shares his thoughts on the biggest names he worked with during his time in Formula One.
One of them was former world champion - Michael Schumacher.
Regarded by many as the greatest Formula One driver, Schumacher is the only one in history to win seven Formula One World Championships, five of which were consecutively.
Schumacher holds the records for the most World Championship titles (7), most Grand Prix wins (91), most fastest laps (77), and the most races won in a single season (13).
According to the official Formula One website, Schumacher is "statistically the greatest driver the sport has ever seen."
"He was a tough driver but he was always fair with me. He never took the p--- when it came to racing; he’d push me to the limit but never over it.
"A controversial character, for sure – just ask Jacques Villeneuve and Damon Hill – but it was always fun fighting with him. Especially when you put him in the rear-view mirror."
The pair enjoyed two spells together on the track.
First, back in 2000 when Button made his F1 debut, Michael Schumacher was dominating the sport.
It was like this for the next four years, after which Fernando Alonso disrupted Schumacher's domination.
Schumacher retired from Formula One in 2006, just to return in 2010 with Mercedes and have three more seasons in F1.
The pair were never fierce rivals - Button was out of Schumacher's league when he started, and when Michael returned to the sport, he was never the same.
But, it seems that Button keeps fond memories of the legend.
Back in 2014, Button was one of the drivers to write a letter of support to Schumacher.
"When I think of Michael Schumacher I think of two things.
"The first is of one my earliest memories of being in Formula One driving out of the pitlane in Melbourne and seeing Michael’s red Ferrari ahead of me scattering the leaves as he drove beneath the trees at the approach to turn three. Even in 2000 he was already a legend.
"The second thing I think about it is that familiar red car snaking about in my mirrors. Michael was such a formidable racer relentlessly competitive - Always There."News Now - Sport News
