Now, I know it's a widespread assumption in the West that as countries modernize, they also westernize. This is an illusion.

Wimbledon 2014 will be my last slam. To be honest, I am already starting to miss professional tennis, having played at the highest level for two decades. It is what has given me my identity, and I will miss every bit of the action. The thought that I will not be playing anymore is daunting.

Golf is the only sport that a professional can enjoy playing with his friends.
