Rafael Nadal is clearly Roger Federer's greatest opponent.
Let's just put aside Wimbledon 2008 for a second and consider some other things about this fantastic match-up.
When these two tennis titans first clashed in 2004, a young Nadal showed Federer that he was the real deal. Nadal went for five sets against Federer, at one point putting the number one ranked Federer down two sets.
Nadal would also end Federer's 56 match hard court winning streak when he beat him in 2006 at Dubai.
In 2007, these two met in the finals of the French Open with Nadal getting the win and his third consecutive French Open title. However, when they met yet again in the finals of Wimbledon, Federer came out on top.
The rivalry continued and led these two men to meet again in 2008 at the French Open. Nadal was once again victorious, getting his fourth consecutive French Open title.
Then they met again at what would be considered their greatest match ever.
Wimbledon 2008 showed the world why this is arguably one of the best rivalries ever in tennis. Federer was ranked number one that year, and Nadal was ranked second. This match put the two best tennis players against one another and went on for four hours and 48 minutes. Federer had always gotten the best of Nadal on the grass courts, but this time, Nadal was the one to come out on top.
These two tennis greats continue to battle it out year after year. Their historic rivalry continues to this day. Nadal has been a serious opponent since he first went against Federer, and no one has ever pushed Federer as far as Nadal has.
Will these two have another historic battle sometime this year?
We will have to wait to find out.
