World number one Rafael Nadal believes that Roger Federer will secure a place in the season-ending ATP Finals in London.
The Swiss pro, who failed to reach a major final for the first time since 2002 this season, is currently seventh in the rankings for next month's tournament, with just eight places up for grabs.
"He's going to go, he's going to qualify," BBC Sport quotes Nadal as saying. "I am sure of that."
Nadal replaced Novak Djokovic at the top of the world rankings at the weekend.
