London: Milos Raonic admits his chastening Wimbledon semi-final defeat against Roger Federer shows the next generation of wannabe stars still have work to do before they can overthrow the establishment.

Raonic and fellow young gun Grigor Dimitrov have long been the most highly regarded of the group of gifted prodigies hoping to end Federer, Rafael Nadal, Novak Djokovic and Andy Murray’s decade-long domination.

With both marching impressively to their maiden Grand Slam semi-final appearances this week, while Murray and Nadal both bowed out earlier than expected, there was a growing feeling that a revolution was brewing.

But those hoping to see some fresh faces holding aloft the sport’s biggest prizes will have to wait a little long after the old guard re-established their supremacy at the All England Club on Friday.

Raonic, 23, was clinically dismissed by Federer as the 17-time Grand Slam winner cruised to a 6-4, 6-4, 6-4 victory just hours after Dimitrov, 23, came up short on the big points in his 6-4, 3-6, 7-6 (7/2), 7-6 (9/7) loss to top seed Djokovic.

It was a savage but potentially valuable experience for the pair, and Canada’s Raonic hopes they will lick their wounds and return stronger and wiser.

“I think guys have the level within themselves. It’s more just an understanding of how to deal with the situation,” he said.

“That’s something I didn’t do well today. That’s probably the thing that I can learn the most from.

“Because I believe I can put myself in the situation again, and the worst part would be to sort of have the same feeling after. I know I can do much better. That’s the most I have to take out of it.”

While Federer and Djokovic, who have 23 Grand Slams between them, have a wealth of experience of how to close out high-pressure matches, Raonic and Dimitrov are both still waiting to play in their first major final.

“It’s obviously a situation I would have liked to have had the opportunity to experience before the semi-final, especially against Roger, who’s played triple digit matches on that court,” Raonic said.

Worrying for the likes of Raonic, Dimitrov and Japan’s Kei Nishikori — the other much-touted member of this young crop — they have all failed to emulate the early successes of Nadal, Federer and Djokovic.

Nadal won his first Grand Slam aged 19, Federer at 21 and Djokovic at 20.

Not since 2002, when Lleyton Hewitt took the title, has Wimbledon been won by someone outside of the sport’s current four superpowers.

The gulf is just as big at the other three majors, with only four of the last 42 Grand Slams won by someone other than those four.

But according to Dimitrov, his win over Murray in the quarter-finals this week and the epic triumph of Australian teenager Nick Kyrgios against Nadal earlier in the tournament should give encouragement to the youngsters.

“This is the first time for me to be in semi-final of a Slam, so obviously to me that’s just positive,” he said.

“I’m not going to over analyse much what’s been happening the past weeks to me because there’s no need for that.

“Of course, I’m going to have to play even better when it comes to matches like that, but it’s a good lesson for me.

“As soon as it comes to a clutch match like those ones against Andy, Novak, this is where I want to get into that next gear and bring all my goods. I think the rest is just a matter of time.”
