Boris Becker published his book a few months ago, but there is still much talk about its contents. The former Wimbledon champion not only spoke about the lack of exuberant characters in tennis nowadays, but also about Roger Federer, Rafael Nadal and Novak Djokovic comparing them to the players who there were when he played.

'Why have players who have not created rivalries? I make an example: Michael Stich and I got along well and everyone knew it. Now we're good friends, but at that time we were happy to say that we weren't friends.

And they asked us every time we had to face each other. It made life more complicated especially because our wives at that time didn't get along. Once I said to the media: 'Look, I've less friends, I think it's normal, and Michael is not one of them, but that doesn't mean that I hate him, he's not one of my closer friends. 'One of the secrets more known on the tour is that Roger Federer and Novak Djokovic don't get along.

The same thing was with me and Michael, they don't hate and respect each other. But when Roger was world no. 1, the young Novak made him angry when he used to call the doctor during matches. It's totally natural that they're not close, they respect each other, but don't get along. 'Who can judge what's good and what's not for tennis? Men's tennis is very popular, the ratings are higher than ten years ago and it has happened thanks to Federer, Nadal, Djokovic, Murray and others.

But I think that ratings could be higher if we were able to see and know more about their personalities and if this means (showing that) that someone doesn't get along, I think it doesn't jeopardizes tennis (players) or their careers.

Obviously sponsors play an important role.' IN THE NEXT PAGE BECKER SAYS FEDERER DOESN'T SHOW HIS CHARACTER BECAUSE OF THE MONEY ALSO READ: Boris Becker: ´I would never stop to coach Djokovic and start working with Federer, Nadal or Murray´
