In press conference Serena Williams said that big wins mean more to her now as she gets older in her career, potentially fewer years left. Does Rafael Nadal feel that at all, they're a little bit more special as he gets older? 'Of course, tennis is not forever', the Spaniard agreed.

'Of course, you know that your chances to play these kind of matches every time are less, remain less chances. But in some way, being honest, I had a very tough injury in 2005. I had the chance to really appreciate all the things that happened to me during my career because I had in different moments tough injuries.

So when you are back, you always appreciate the things that happens, and have more value, more personal value, when you come from tough moments, no? Yeah, of course for me, I played a lot of long and tough matches in my career.

That's one more today. I like this feeling, but at the same time you feel tired after that. But, winning, losing, I lost in Wimbledon a match like this, today was for me', Nadal stated after his win over Dominic Thiem on Tuesday.

'In some way when you give everything that you have, win or lose, is just that someone have to lose, someone have to win, that's part of the game. But the personal satisfaction when you give everything and you play with the right attitude is the same.

For me, very happy to be in the semifinals. But being honest, after Wimbledon, I was happy about my attitude and my match there. When you win or when you lose like this, you come back home with the feeling that you did all the things that you can do.'
