Wimbledon on day three: Who said what at the All England Club

"We have a very romantic relationship."

-- Novak Djokovic on Centre Court, where he hasn't lost since 2013.

"Not getting crazy and let's say -- how can I explain it -- not being probably a selfish kid on the court. Sometimes I can be."

-- Daniil Medvedev vows to behave himself after receiving a warm welcome from the crowd following the ban on Russian and Belarusian players last year.

"Oh my God, David Beckham is watching me play tennis right now. I think everyone gets excited when David Beckham is around."

-- Starstruck British player Jodie Burrage after losing to Daria Kasatkina on Centre Court.

"For me, money is not the number one priority."

-- Kasatkina says she will not be tempted to play a WTA event in Saudi Arabia.

"Am I playing Superman right now?"

-- Frances Tiafoe stunned by Wu Yibing's battling qualities after the Chinese player took a medical timeout before losing in three sets.

"I'm just going to throw a curveball, you guys won't really think. I'm going to put Andy Murray in there. Very dry humour. Very, very funny. You guys think he's boring or whatever, but I think he's hilarious. Man, I love that guy."

-- Tiafoe ranking the British star high up on the list of tennis jokers.

"I was crying during the breaks, trying to figure out what to do."

-- Marta Kostyuk of Ukraine before coming back after the interruptions to defeat Greek eighth seed Maria Sakkari in three sets.

"No, I don't remember, especially in the last couple of months probably I didn't."

-- Kostyuk responding to a questioner who wanted to know if she had enjoyed her vacation in Ireland and Iceland. She had not been.

"There is poetry on grass."

-- Stefanos Tsitsipas after his five-set win over Dominic Thiem.
