Breaking News: Coco Gauff’s former coach tells Victoria Mboko what he doesn’t like about her game, ‘exactly the same issue as Coco’…see more

“She double faults a lot. You know, after she won that tournament in Canada, she literally lost first round, like, six in a row.

Petkovic added, “The thing is, what you said was so interesting, because the one difference between her and Coco is she goes for broke on her first serve. So she’s still ace leader, you know, she has a lot of aces.

“And then sometimes she also has 12 double faults, but at least she sort of balances it out with a lot of free points when she does find her rhythm.” After exiting the United Cup, Mboko is still entered into one more tournament ahead of the Australian Open.

The American star has now won three of her four singles matches at the United Cup, having secured victories earlier in the tournament over Solana Sierra and Maria Sakkari.

Gauff increased her winning streak against Swiatek to four matches, with the head-to-head now 11-5 in favour of the Pole.
