AEGON Championship, Queen's Club - Fact File

What is it?

A notable form guide for Wimbledon for starters. During its rich history, there have been seven different players to complete the Queen's Club-Wimbledon title double in the same year, including John McEnroe (1981, '84), Jimmy Connors ('82), Boris Becker ('85), Pete Sampras ('95, '99), Lleyton Hewitt (2002), Rafael Nadal (2008) and Andy Murray (2013).

Which players have been most successful?

In 2013, Andy Murray joined an elite group of players to win a quartet of titles in London, including McEnroe, Becker, Hewitt and Andy Roddick.

Who is playing?

Andy Murray - The Scottish World No 2 enters the tournament looking for a record fifth win. On the strength of his Roland Garros form, don't bet against him getting a morale boosting win ahead of Wimbledon.

Stan Wawrinka - Defeated by Murray at the semi-final stage in Paris, Wawrinka has never quite got his grass court game going, falling at the quarter finals at Wimbledon for the last two years. Recently added former SW19 champion Richard Krajicek to his camp.

Milos Raonic - The big-serving Canadian, now World No 9, came into this event ranked No 8 last year but lost in the quarter finals to GIlles Simon.

Nick Kyrgios - The Aussie wild child, who has Lleyton Hewitt in his corner, might have pulled out of the Australian team for the Olympics but he will bring colour to Queen's Club.

Juan Martin del Potro - The giant Argentinian is attempting to recover his fitness after three years away from the tour. Queens will offer an indication of where he is ahead of SW19.

Jamie Murray and Bruno Soares - The elder Murray sibling and his Brazilian partner will be among the favourites for the doubles competition, with Andy Murray also scheduled to play alongside Scotland's Colin Fleming.

Kyle Edmund/James Ward/Dan Evans/Aljaz Bedene - The lesser lights of British tennis will also attempt to make the mark at Queen's. Ward reached the semis as a wild card in 2011.

Who isn't?

Rafael Nadal - The Mallorcan, a previous winner of this trophy, hasn't recovered from the injury to his left wrist which saw him leave Roland Garros early. Won't play at SW19 either.

Novak Djokovic - The imperious Serbian World No 1 doesn't seem to need warm-up events, preferring to spent his lead-up time locked away in practice.

Roger Federer - The Swiss legend will grace his usual grass court warm-up event in Halle in Germany, where he has a long term contract.

Kei Nishikori - The Japanese is another who is on the bill at Halle, alongside Tomas Berdych, Dominic Thiem, and Alexander Zvereve

Jo Wilfried Tsonga - The Frenchman has pulled out of the warm-up tournament because of an adductor injury but any French fans will at least be able to watch Richard Gasquet.
