Serena Williams' conqueror Sabine Lisicki believes the best is yet to come ahead of Tuesday's quarter-final clash with Kaia Kanepi.
Ranked 24 in the world, few had given the 23-year-old German a chance of beating world No 1 Williams on Monday, but she won 6-2, 1-6, 6-4 on Centre Court.
Less than 24 hours on, she will face Kanepi at the quarter-final juncture and is in a understandably confident mood.
"I never played her before," said Lisicki, who saw her mixed-doubles match cancelled on Monday night.
"My coaches will do some scouting. We'll watch some tapes and get me ready for that match.
"I feel great. I really played four very, very good matches. I think I played better with each match. I get more and more confident with my strokes, as well as my game.
"I am looking forward to playing again."
Kanepi secured her place in the final eight by overcoming home favourite Laura Robson 7-6, 7-5 on Court One.
Expecting a hostile reception from the home fans, the Estonian said: "I think the crowd wasn't that bad actually.
"When she won a point it was a bit louder than normal but they didn't clap when I double-faulted or anything. I think it was really good.
"My serve and baseline game were good and I guess I will have to hit hard in my next match, that's always important on grass."
Whoever wins Tuesday afternoon's duel will face a tough semi-final against either fourth seed Agnieszka Radwanska or sixth seed Li Na.
They are followed onto Centre Court by 2011 champion Petra Kvitova and Kirsten Flipkens.
Czech Kvitova beat Spain's Carla Suarez Navarro 7-6, 6-3 on Monday and Belgian Flipkens won by a near identical margin.
Their potential semi-final opponents are Marion Bartoli and Sloane Stephens, who received an endorsement from outgoing champion Williams.
The only American left in the Wimbledon singles, the 20 year old overcame Monica Puig 4-6, 7-5, 6-1 and was tipped by the world No 1 as her potential successor.
"That's very nice of her," Stephens said. "I don't know. I have a couple more matches to go till that happens.
"I am just going to go out and play my hardest and see what I can do."
