Simona Halep believes she is 'starting to believe' in herself again after she moved into the Wimbledon semi-finals.
Halep is a two-time Major winner, including a Wimbledon title which she won back in 2019.
Since then, though, she has struggled mentally and she suffered an on-court panic attack last year.
She has now made a coaching change, linking up with Serena Williams' former mentor Patrick Mouratoglou, and it appears to be helping her regain her game.
The Romanian beat Amanda Anisimova 6-2, 6-4 on Centre Court to get into the last four at Wimbledon, and she says she can feel her confidence starting to return to her.
"I am definitely playing my best tennis [since winning Wimbledon in 2019],” she said.
“Last year I struggled a lot and now I am just trying to build my confidence back. (I'm happy with) my tennis here and all I need to do now is to start to believe in myself.
“It’s great to be back in the semi-finals. I am very emotional right now because it means a lot.
“I played a tough opponent today who could crush the ball in the end and I didn’t know what to do. I just believe in myself. I believed until the end that I could win.
"I had to stay strong on my legs - they helped me today. I also needed my serve - everything was good, and it finished well."
Simona Halep will face Elena Rybakina of Kazakhstan in the Wimbledon semi-finals after she came from a set down to beat Ajla Tomljanovic 4-6, 6-2, 6-3.
"It is amazing," Rybakina said. "I am really happy to be into the semi-final. It was a really tough match.
"I started a bit slow, I didn't serve that well. Maybe I was nervous. She played really well and was defending really good but I just tried to focus on my serve and try to find my way and in the end I found it."
On her upcoming match against Simona Halep, she added: "It is a big challenge for me. We have already played a few times and it was a tough battle."
