Federer can be off for six months but knows how to win matches.

People talk about the drama of the set that goes on and on. But it leaves one guy exhausted for the next round, it's horrible for the players waiting to come on court, and it has the potential to mess up the schedule for everyone.

I don't think there is anything missing from Tsitsipas.

Maybe we can see more men's and women's combined events so the young players can be marketed better.

More than half of the matches are won in the dressing room for him. The guy he's playing against is sitting in the locker-room thinking 'oh my God, I'm going to play Rafa Nadal on clay in five sets, that's going to be painful.'

There is no added pressure to play a Swede.

I am really impressed with Dominic Thiem's patience at times.

Rafael Nadal, I see no demons in him. None. Unless he picks up the racket with his right hand.

I like to camp and to not have to check in to airports and hotels and I love to just drive, man.

Nadal is just more at home on clay. It looks like he feels safer on clay courts. He can get to a few more balls, he can play a bit further behind the baseline when he defends, and he's also able to get the ball to bounce higher. It's unbelievable.

I think when you can beat Novak Djokovic in the final of a Masters tournament, you are going to be OK.

I love the freedom of the road.

There's no way you can go out there and have a killer instinct on court, be selfish on the court, when there are more important things going on in your life, or in your heart.

If an athlete like Michael Jordan played tennis, he would be the best - he's flexible, not too bulky, and has unbelievable hand-to-eye coordination.

Svitolina moves a little bit better than Ostapenko but Ostapenko goes for it a little earlier in the rallies. The way she plays she can take you out of the equation.

At Wimbledon if it is slightly wet you don't even play the match. At the French Open you need to just get on with it and somehow adjust.

Everyone has a temper, but in Sweden, no one throws a racquet or screams. We show more manners and common sense. This is a game, not war.

I was a really good ice hockey player when I was a kid. Now in the aftermath I think I wasn't maybe big enough, and I couldn't have put on enough muscle to actually be able to play with the better guys, but I was a really good skater.

There's definitely a lack of self-belief in many players, which is the only complaint I have about men's tennis.

If it doesn't mean more to a normal human being like Dan Evans, who could change his life and career by winning not a gold but a bronze medal for Great Britain, if he doesn't want to take that chance, I would say something is wrong with the Olympics in what it's worth in tennis.

The biggest mistake we usually tend to make with young players is over-coaching.

To me, Dan Evans is an example of somebody that puts the clock back a little bit and tells everybody: 'Listen, tennis is not a freak sport where you need to have rich parents, who sit in your players' box for every single week of the whole year, and you need to talk to your coaches' box between every shot.'

Sure, it comes with a lot of bonus rewards, whatever it may be, some of it may be financial. And it is great to have been No 1 in the world, when you get a bit older you can reflect on it. But I was No 1 in the world before I actually was No 1 in the world, in my mind at least.

I still rate my first victory in the French Open at Roland Garros as my best win ever.

Andy Murray's already done what is needed for British tennis, which is ignite it. There's a person, there's a player that kids want to be like.

Miloslav Mecir - best anticipation of any player in our generation for sure. The most flexible... and then crazy good hands. He is the best player in the world to not have won a slam, for sure. No question in my mind. He should have won three or four.

Ninety five percent of the field is not competitive when Nadal is playing.

Only so many can succeed. Only one can be number one.

I'm a useless guitar-player. When I put myself in a band I immediately became its weakest part. I was like my forehand volley at tennis.

It is basic, serve at the weak point of your opponent.

Del Potro is one of these miracle men he can come up with these matches where you least expect it and he pulls something out of the bag. I have no idea what it is but he becomes a magician.

The conditions change so much at the French Open, you know, you have to be prepared for something you really don't know what it is. You can practice in the morning and it's fine, and the weather is great then you come to play in the afternoon and it is drizzly and the conditions are totally different.

I love camping out, I love teaching tennis.

I'm not Borg Two, I'm Wilander One.

I really enjoyed playing Yannick Noah - he was and still is my favourite. In the heat of the moment he was very fair and very physical. He was strong, big and he moved unbelievably well. He was also mentally tough.

I play a lot of golf and I'm in a little ice hockey league at home in Idaho.

I was 7 years old and my dad gave me a wooden tennis racket.

Nick Kyrgios, physically, is a monster. When he is on the court and he runs, he flies. And he has got a massive arm.

The point is to win the biggest tournaments and beat the biggest guys head to head. Then, if the computer ranking works out that you are No 1 in the world so be it.

Tennis is a running game, not a hitting game - it's not golf.

I decided to work really hard in 1987. I hired Matt Doyle, a former pro player, and he helped me with my physical training. Lendl was the first to focus on that. He used to be weak, physically and mentally.

He didn't have the best shots but the intensity of the match and the positive energy you got from playing Yannick Noah was something I didn't get from anyone else.

The Davis Cup should be home and away from the semi-finals as a minimum, I would say even the quarters.

The slide is tennis.

I think it's bad in a way for junior players and college players to feel they must be number one.

I love my life. I commentate for Eurosport, so you could say I've reached the final of every grand slam since 2002 when I started that. I love what I do, and I love playing tennis with amateurs, regular guys, helping to teach them to enjoy tennis more.

I always feel that if you were the best in any generation, you most likely would have been close to the best in any other generation too.

I play the guitar.

I hardly ever watch TV and when I do it's sports. I'll occasionally stick on some old episode of 'Fawlty Towers' or something.

In Sun Valley, people play tennis and then go for a hike. You should be too tired to go for a hike!
