Stefanos Tsitsipas has said he and a new generation of tennis players are eager to stop Novak Djokovic's dream of a "Golden Slam" calendar.
The world number four took two sets away from Djokovic in the final of the French Open, before the Serbian won the next three and claimed the title.
Djokovic also defeated Daniil Medvedev, considered one of the ATP's big three players, at the Australian Open in February.
"He's a complete player. He has the talent to do it ['Golden Slam']," Tsitsipas said at a pre-Wimbledon news conference on Sunday.
"Young generation, we are hungry and we want something similar. Obviously we want to stop him and we want to stop that dream of him."
However, the Greek player admitted that pushing Djokovic aside will not be easy.
"It's going to be difficult," he said. "Me personally, I find it very difficult to play against him.
"He's someone who thinks he's the best, so that's why he's playing that way. The grass court is a surface he's confident on and he's playing well."
Djokovic has been given a favorable draw at Wimbledon with his first-round match against British wildcard Jack Draper. He is also at the other end of the draw with Roger Federer.
Tsitsipas will face Frances Tiafo of America in the first round.
"I have a long way to go to face him in this tournament," said Tsitsipas. "It won't be easy for either of us."
