Tennis LIVE: Emma Raducanu shows true colours as Novak Djokovic gets emotional

Wimbledon chief Sally Bolton has confirmed that security measures will be ramped up at SW19 this year.

It comes after Emma Raducanu was targeted by a stalker during a match against Karolina Muchova in February.

Bolton said: "The safety and wellbeing of all of the players is our absolute top priority.

"I think the recent incidents coming to light certainly recognise the concern generated by that.

"But we have in place, and have had for many years, processes for ensuring the safety of our players.

"That is in liaison with law enforcement agencies, specialist security teams and we liaise with both tours.

"It is a bit like the broader security for the grounds. We are putting in place measures that are reflective of the threat and risk profile at the time."

Novak Djokovic has revealed that he has always felt closer to Rafael Nadal than Roger Federer in a candid interview.

He said: "Just because someone is my biggest rival doesn't mean I wish them harm, hate them, or want to do anything else on the court to defeat them.

"We fought for the win, and the better player won. I've never said a single bad word about them [Federer and Nadal] and never will.

"I looked up to them and still do, but I've always gotten along better with Nadal."

Here's a look at what's in store today at Queen's Club...

Novak Djokovic has emotionally admitted that he felt like an 'unwanted child' in comparison to Rafael Nadal and Roger Federer.

He told Failures of Champions: "I acted and still felt like an unwanted child.

"I asked myself why that was. It hurt me. Then I thought the fans would accept me if I acted differently, but that wasn't the case either.

"I was never as loved as Federer and Nadal because I wasn't supposed to be there.

"I was the little guy, the third guy who came along and said: 'I'm going to be No 1'. Many people didn't like that."

Emma Raducanu sent a classy message to Katie Boulter after surpassing her doubles partner as Britain's top-ranked female player.

Following her victory over Rebecca Sramkova at Queen's Club, she wrote a message on the camera lens which read: "Long live Boultercanu."

Raducanu also revealed that she wanted to rekindle her partnership with Boulter, having enjoyed their brief run in the doubles tournament.

"I really want to play with Katie again in the future," she said. "Maybe over the grass, but for sure in the future."
