The International Tennis Federation president David Haggerty says the Davis Cup can become the number one team event in tennis. Haggerty has overseen a revamp of the tournament which is said to be worth $25m-a-year for tennis development around the world.
The new-look Davis Cup will take place over the course of a week with Madrid chosen to host the first two finals.

Meanwhile, the ATP is planning a World Team Cup in Australia in the first week of January from 2020 and if that goes ahead it will come just five weeks after the first staging of the new 18-team Davis Cup finals.
Haggerty says that negotiations are ongoing with the ATP “to run one team event – the best that we can”.
“We think Davis Cup with its 118-year history has a great reason to be that event, and I think by working together with the ATP, and tennis …why not?” Haggerty told BBC Sport.
