Alexander Zverev is determined not to go down as the "best player of all time to never win a grand slam".

Zverev was downed 6-3 7-6 (7-4) 6-3 by a dominant Jannik Sinner in the final of the Australian Open on Sunday.

It is the third time the German has lost a major final.

With a 107-36 record, Zverev has a 74.8% win ratio at the grand slams. That is the best win percentage of any man not to win a major title in the Open Era (minimum 10 matches played).

And Zverev does not want to consider the thought of ending his career without a grand slam crown.

"I'm doing everything I can. I'm working as hard as I ever did," a downtrodden Zverev told reporters.

"I think I'm doing all the right things off-court. I think I'm practicing the right things, but I lost in straight sets today.

"Those are facts. That is a fact. I lost to Jannik in straight sets today.

"I don't want to end my career as the best player of all time to never win a grand slam, that's for sure. I'll keep doing everything I can to lift one of those trophies."

Sinner appeared to console Zverev prior to the trophy presentations.

"I was quite down," Zverev said. "I was quite emotional also at that stage. I think he saw that.

"He said that I will definitely lift one of those trophies in my career. I'm too good not to. That's his words.

"It was a bit of a tough moment for me. I really thought I had a very good chance because I was feeling good. I was feeling the ball quite well. I felt like I could compete.

"So it was just a difficult moment for me. I mean, now for the third time, seeing somebody lift the trophy, me standing next to that is difficult because there's nothing more I want than to be able to hold one of those trophies in my hands."
