World number one Rafael Nadal is hoping that he can end his long wait and finally win the ATP World Tour Finals in London this week.
The Spaniard has won all four Grand Slams over the course of his career, as well as Olympic gold and a record 26 ATP World Tour Masters 1000 titles but has never managed to secure the crown of the event at The O2.
"This is the title I'm missing," Nadal told the press. "I wish I could get this title.
"Several times I played at a high level here, but I ran into those who are perhaps the best indoor players in history."
Nadal gets his campaign underway on Tuesday when he faces compatriot David Ferrer.
