Ever wanted to ask Stan Wawrinka how to attack a one-handed backhand? Or what it takes for Caroline Wozniacki to stay fit all year round?

Mark Hodgkinson, former tennis correspondent for The Telegraph, has asked them for you, along with hints and tips from dozens of players, former pros and coaches to improve your tennis and to gain a new appreciation for the sport.

Pete Sampras is on hand with the secret behind disguising your serve; Roger Federer’s mother Lynette offers advice to tennis parents.

The list is endless – among the players are Andy Murray, the Williams sisters, Maria Sharapova and the Bryans. Former world No.1s Boris Becker, Steffi Graf and Martina Navratilova all chip in, as well as coaches Toni Nadal, Patrick Mouratoglou, Judy Murray and Darren Cahill.

We have five copies to give away. For your chance to win, simply tell us what tennis tip you'd most like to receive, and from whom and we'll pick our favourites.
