Monica Seles

Since I retired, I very much enjoy watching Serena Williams play. While I was playing, she was one of the toughest players I ever faced. Her ground strokes are so solid, her serve is one of the most powerful in women's tennis, and mentally she is just so strong.

It is only when you watch the dense mass of thousands of ants, crowded together around the Hill, blackening the ground, that you begin to see the whole beast, and now you observe it thinking, planning, calculating. It is an intelligence, a kind of live computer, with crawling bits for its wits.
