Rafael Nadal says that, even though it’s a great win, he still has plenty of things to improve in his game (also says that has no limitations on the serve anymore, and is slowly building it back up):
“You get excited, but the reality is that it's one match, in two days we'll start again and the ‘glass’ of energy and confidence is filling up, but today I'm far from being able to aspire to amazing things. I think it's an important step forward, that with small steps you build big things, but unfortunately the reality is often different. That doesn't mean that I don't get excited and that I have no hope for the future.
If I didn't have hope, I wouldn't be here. If I'm here, it's because I hope that things will get better and because it keeps getting excited and motivated by playing tennis."
