Martina Navratilova was thrilled to see Emma Raducanu back to her best at this week’s Miami Open and the tennis great has offered her advice on how the Brit can carry that momentum forward.

Raducanu, 22, won four matches in a row for the first time since her 2021 US Open triumph, as she reached the last-eight of the prestigious Miami Open.

She ultimately lost a tight match against world No 4 Jessica Pegula 6-4, 6-7 (3-7), 6-2 but played her best tennis in years during the tournament.

It was hugely encouraging for Raducanu despite a scare at the end of the second set when she complained of dizziness, but she soldiered on.

Navratilova, a winner of 18 singles Grand Slam titles, praised Raducanu for overcoming her physical struggles to claim the second set but remains concerned about her health.

‘It was amazing,’ Navratilova told Sky Sports.
