2019 Madrid Open QF Rafael Nadal bt. Stan Wawrinka  6-1 6-2

Next opponent - Stefanos Tsitsipas

"It was a very positive match. I'm very happy with the way that I played and in general terms, it was a great performance."
 "I'm happy, it was an important moment for me and I'm really happy to be through this way."

"Wawrinka had won three matches pretty well. He's been playing really well on clay in the past few weeks and he also beat Nishikori, who is also a very tough player, so he was playing really good."
"I was expecting a tough match today. I knew that I had to play a little better and fortunately it was a good day for me. I have been lucky. It was an important day for me [because] I have been able to work through to the next stage. I have done really good things today."
"He was trying to with his shot to find my backhand, but I was returning good on the backhand so maybe he didn't find his place on the court and overall, I was solid." 
"On defence, I felt that I had a lot of power in my legs because I wanted to defend properly and my opponent needed better shots in the next shot to make, to harm me a bit more. And I had a bit more confidence on the winning shot."

On Stefanos Tsitsipas:

"He's playing well. He won last week in Estoril and he's already won a lot of good matches this week. He comes to that semi-final with plenty of confidence. It's going to be a tough one, I hope to be ready for it." 
"I'll need to play my best. Today was a good example. I need to continue tomorrow, that's the goal."
