#3 Controversies
Just like everything in life both the legends of the sport have had their careers littered with controversies here and there. For Schumacher, the controversies began with him intentionally driving into Jacques Villeneuve in Jerez in 1997(to take him out of the race and win the championship) only to get penalized and thrown out of the championship.
Then there was the incident where he parked the car at the Rascasse to block Fernando Alonso from taking pole. Lewis on his side has been guilty of infringements himself as throughout his career, he was part of the Liegate in Melbourne in 2009 or the illegal Tyre test that Mercedes undertook in 2014 or for that matter coming out in the media and stating that he gets punished by the stewards "maybe because he was black". Throughout their careers, both were mired by controversies here and there and still found a way to dig deep and keep winning.
