What do Muhammad Ali, Sharapova and Carlsen have in common?

Porsche! Your read right. These athlete stars featured a Porsche commercial. "Greatness comes from within.. you against you... until the greatness version of you..."

The commercial is from the end of 2015, but maybe you haven´t watch it. I just found out about it today. Once again, chess becomes markatable and that is a big win for chess!
