Maria Sharapova has revealed that she is delighted to have reached the quarter-finals of Wimbledon for the first time since 2011.
The Russian defeated Zarina Diyas in straight sets to advance to the last eight, where she will take on Coco Vandeweghe.
However, Sharapova has conceded that she will face a tough test to progress to the latter stages of the competition.
"The further you get, the tougher it gets, so I really had to be ready for her," Sharapova told BBC Sport.
"Coming into this tournament I didn't have a warm-up event, so I wanted to start off strong to give myself a good chance. I know it only gets tougher from here.
"It's a great position to be in. I lost at this stage last year so I'm happy to go a round further and I hope it continues."
The 28-year-old won the competition back in 2004.
