Ruud on Nadal: "Thanks for inspiring me".

Since announcing his retirement, Rafael Nadal has received a huge number of tribute messages from all kinds of players and people in the tennis world.

For example, Casper Ruud thanked the Spaniard for his contribution to tennis: "I still remember when I saw you win your first French Open.

I was 6 years old and, from that moment on, I dreamed of becoming a professional tennis player. Every time I had the chance to see you play, it motivated me to become better so that one day I could meet you or play against you.

Hard work has paid off, just as you've shown every day of your career.

Thank you for inspiring me and millions of other kids around the world, and for everything you've given to the sport.

Your legacy will continue to inspire and I hope you enjoy your well-deserved rest and the next chapter of your career."
