Jo-Wilfried Tsonga joins Andy Murray in Queen's Club line-up

Former finalist and world number eight Jo-Wilfried Tsonga has confirmed he will be among Andy Murray's rivals at Queen's Club in June.

The Frenchman, 27, will join Murray, world number six Tomas Berdych and world number seven Juan Martin del Potro at the Aegon Championships.

Murray beat Tsonga in the 2011 final, as well as last year's Wimbledon semis.

"It's great what he has achieved and he deserves it, but to play against him is a nightmare!" said Tsonga.

"You feel like the ball is coming back all the time. When I play against him I know I am the outsider, and I will always respect him." 

It will be the fourth time he has played at Queen's Club, having made a major breakthrough by coming through qualifying to reach the last 16 on his debut in 2007.

"It is full of history," he said. "For me you can not have a better tennis tournament. It's a special place. I entered the top 100 for the first time at Queen's Club when I beat Lleyton Hewitt, who was the defending champion.

"It was also the first time that I did my 'dance' celebration (points his thumbs to his back) and the British people loved it! For me it's a pleasure to be there. I've always played well on grass, I expect to win tournaments on it, so we will see what happens at Queen's and at Wimbledon."

Tsonga began working with Australian Roger Rasheed at the start of this year, and the coach believes grass suits the Frenchman's game.

"When you are making changes with a player, you can't just click your fingers and make a difference," said Rasheed.

"When we got together I told him it would take a while to come together, but working with Jo is exciting. He has the game to make a real impact. He can be dangerous anywhere, but particularly on grass, because it's natural to him."

Argentina's Del Potro, 24, will be a major threat after showing he is capable of repeating his US Open winning form of 2009 when he beat Murray and Novak Djokovic in Indian Wells last month.

Berdych's only previous visit to Queen's, in 2005, ended in a first-round defeat and the 27-year-old Czech has since gone to Halle in Germany for his grass-court preparation.

However, this year he has altered his schedule this year as he attempts to go one better than that defeat by Rafael Nadal at Wimbledon three years ago.

"I think it could be a good advantage to be in London to get used to the conditions and to those great courts, and I think this is exactly what I need before Wimbledon," he said.

"The experience of reaching the Wimbledon final [in 2010] was great. It showed me a lot of things - that I'm able to play really well through two weeks, which is very tough. I now have experience of a Grand Slam final and I hope one day I can be able to profit from that."
