Alcaraz on his elimination in Doha: "I don't know what I could have done better".

Carlos Alcaraz fell to Jiri Lehecka in the quarter-finals of the ATP 500 on Thursday.

Beaten for the second time this season and for the first time since Melbourne, the world No.3 gave his impressions of the defeat in a press conference:

"I've spoken to my team and my coach, and I honestly don't know what I could have done better.

Perhaps I could have served a little better at certain moments, and there were also a few points that I didn't play well.

But apart from that, I don't know. I have to give credit to Jiri, because when he was behind on the score, at 4-2 in the third set, he didn't give up.

It came down to one point (4-2, 40-30, double break point). That's what makes tennis so difficult. The ball stays in the net for a few centimetres. It could have changed everything.

I could have done better at 4-3, but he started to play in an incredible way. He was very aggressive and made no mistakes. I've got to be more consistent in those hot moments. But all credit to him."
