Djokovic on Alcaraz: "I'm sorry for him, I understand it's not comfortable".

Djokovic defeated Carlos Alcaraz on Tuesday in four sets at the Australian Open.

While the Serb had to deal with physical problems, these incidents had an impact on Alcaraz's concentration.

Djokovic reacted to this in a press conference: "I noticed that he had lost his concentration. I tried to take advantage of this, by taking the initiative in the exchanges and taking advantage of his doubts.

I've also been in a situation where my opponent had problems but kept on playing, and as the match progressed, he started to feel better.

That's when you start to panic. I understand that feeling. I wasn't feeling well in the second set, but I tried my shots, being more aggressive.

I started to feel better as the match went on, especially towards the end of the second set.

I felt that the injury wasn't too restrictive, honestly, it was normal.

I'm sorry for him, I understand that it's not comfortable to play against someone who you're not sure will give up or not.

I felt he was looking at me more than himself. I got the break, I won the set, and he hesitated on the baseline, started making a few more errors, and I started playing more freely."

Djokovic will face Alexander Zverev this Friday for a place in the final.
