Three-time Grand Slam champion Stan Wawrinka and former champion Grigor Dimitrov have been confirmed for the Aegon Championships at Queen’s Club in London.

Dimitrov claimed the Queen’s Club title in 2014, before going on to reach the last four at Wimbledon in his first-ever Grand Slam semi-final appearance.

The Bulgarian star feels he is now a “better player” than he was in 2014, having reached the semi-finals of the Australian Open this year and claiming titles in Sofia in his homeland and in Brisbane prior to the first Grand Slam of 2017.

Wawrinka will be hoping for a better showing than he produced at the 2016 edition of the tournament, having been beaten in the first round by Fernando Verdasco.

The Swiss star also failed to make an impact in 2015 after landing the French Open title as he fell in the second round.

Andy Murray will be involved at Queen’s as he has committed to the tournament for the rest of his professional career, with Rafael Nadal also set to compete.

The players will use the event in June as preparation for Wimbledon, where world number one Murray is the defending champion.

Murray and Novak Djokovic are rated as the 2.75 joint favourites ahead of Wimbledon, which takes place between July 3 and July 16.

Dimitrov is 21.00 to claim the Wimbledon crown and Wawrinka is available at 26.00 as he seeks the one Grand Slam crown missing from his collection.
