# Tennis: World number three Alexander Zverev has set his sights on winning a Grand Slam title next year. The 24-year-old German finished this season in the best way possible when he claimed his second ATP Finals trophy by defeating Russia’s Daniil Medvedev in Turin, Italy. Serbia’s Novak Djokovic currently leads the world rankings by nearly three-thousand points over Medvedev and nearly four-thousand points over Zverev. However, the German believes the number one ranking is also not out of reach next year.
