Emma Raducanu and Carlos Alcaraz in disagreement over first date kiss

Emma Raducanu and Carlos Alcaraz disagree on whether couples should kiss on their first date.

The pair teamed up in the US Open mixed doubles competition last week, but were knocked out in the first round by Jessica Pegula and Jack Draper.

Raducanu and Alcaraz have long been friends, with both players shutting down speculation of a potential relationship after their mixed doubles partnership was announced in June.

That hasn't stopped questions continuing to be asked of the pair, though, with a Wimbledon reporter widely condemned in July for asking Raducanu's fellow Brit Cameron Norrie if he was dating her.

Now, in a new feature with Sky Sports, Raducanu and Alcaraz were among a host of tennis stars to be asked a series of questions about 'controversial topics'.

The players had to answer by showing a card reading 'friend' for agree or 'foe' for disagree, before having the option to explain their choices.

The first question was whether people who are dating should kiss on their first date - and both Raducanu and Alcaraz had differing responses.

Alcaraz answered: "Kiss on a first date? Jesus. Okay, I agree, yeah."

Raducanu, meanwhile, quickly held up the 'foe' card.

The pair also disagreed over whether to put pineapple on pizza, with Raducanu laughing as she held up the 'friend' card: "I'm so sorry!"

Alcaraz debuts new look at US Open

Upon arriving on the practice courts on Monday ahead of his US Open first round match, Alcaraz left everybody stunned by debuting a new look.

The Spaniard has completely shaved his head, and was wearing a Nike vest that brings back memories of mid-2000s Cristiano Ronaldo.

Speaking in his pre-match press conference, fellow US Open star Francis Tiafoe said: "It's definitely terrible. He's my guy though. But yeah, I don't know who told him to do that, but it's terrible."

In a separate interview, Alcaraz responded: "He likes it! I know he likes the haircut. He told me. I've not been hearing anything about comments coming from his mouth."
