Simon says that they can understand their positives and negatives and work to hone these during a period with no tennis since March.

"I think this period is the best for middle-aged players, guys between 25 and 30. I believe they already have experience on the ATP Tour and it’s the right moment for them to improve their game and to do a “check-up” of what happened in the first part of their career," said Simon during his blog on the ATP website.

"They are starting to know a bit more about themselves as people and players. Middle-aged players are starting to understand the limitations they had before.

Now they've had the time to work on those things, while still having the energy to do so. They’re still very young and healthy. For them, it will be great."

He has also spoke about his own training regime as he goes towards the twilight of his career and how he needs to ultimately adjust it.

"For the older players, I think the key in this period is to work a lot with the body. It is most important to stay healthy and to try to work enough to stay in good shape, but not working too much, and take the time to prevent injuries.

Your body is not the same as when you were 20. Then you were able to go four hours every day no matter what you are doing and have no problem. For us older players, it’s a bit different now."
