Even a mouthwatering battle for the world number one ranking between Rafael Nadal and Roger Federer has been scotched with Spaniard Nadal having taken an unassailable points lead. Zverev, the 20-year-old German, has won five titles in a stunning season and catapulted to third in the world rankings. A year ago Federer and Nadal were both missing from London and many thought they might never be back with rackets in hand. Should Nadal declare himself ready and able he will face Goffin in the Pete Sampras group on Monday evening. Dimitrov and Thiem are also in Nadal's group while Federer kicks off against Sock on Sunday before Zverev makes his eagerly-awaited debut against Cilic.
