KEY POINTS:
There's no Rafael Nadal, but Generation Next poses a serious threat to Roger Federer's tilt at a Tennis Masters Cup hat-trick from tomorrow. Britain's Andy Murray heads a list of four new faces, including Jo-Wilfried Tsonga, Juan Martin del Potro and Gilles Simon, at the least predictable season finale of recent years. Murray is the man in form after a breakthrough spell in which he reached his first Grand Slam final and won back-to-back Masters series titles to go fourth in the world rankings.
