World number two Rafael Nadal has been knocked out at the semi-final stage of the Paris Masters, toppled by German Alexander Zverev in a stellar 6-4 7-5 victory. It’s Zverev's second successive win against the 20-time Grand Slam winning Spaniard who was seeking a maiden ATP Paris title to follow up his Roland-Garros victory in the French capital in October. World number seven Zverev sealed victory in one hour and 39 minutes and now faces third-seeded Russian Daniil Medvedev in Sunday’s final.
