Rekindling their always contentious rivalry, No. 2 Andy Murray meets No. 5 Rafael Nadal for a spot in the semifinals of the ATP World Tour Finals on Wednesday afternoon in London.

The Scotsman won the last clash in the eight-year long battle with a straight sets victory at the Madrid Masters earlier this year, but Spain’s Nadal owns the all-time mark at 15-6 and he’s beaten Murray on every surface.

Murray’s also attempting to lock down the No. 2 overall ranking, and would qualify for the tournament’s final four with a win over Nadal and if Stan Wawrinka fails to win in straight sets in the evening’s match in the round-robin.

"It would be obviously nice to finish number two because I haven't done it before,” Murray said according to BBC Sport, “but it's not a goal that I'd set for myself at the beginning of this year or throughout the whole year really."

Nadal, 29, looks to wrap up what’s been a trying season for him, going 58-19 with three singles titles for the season, but he just blasted past this year’s French Open winner Wawrinka in straight sets 6-3 6-2. Nadal has yet to win a title since taking an August title on clay in Hamburg.

"It's an opportunity for me to compete against the number two of the world, a player who had a great season, a fantastic player in every surface, but especially in this one he likes to play," Nadal said. "I'm excited to play that match. I only take it as an opportunity to play against him, to try to play a good match. I'm going to try."
