Australian Open quarter-finalist Ekaterina Makarova has said that she is better prepared for her last-eight encounter than she was last year.

The Russian triumphed 7-5 6-4 over German fifth seed Angelique Kerber to set up a match with either Maria Sharapova or Kirsten Flipkens.

Makarova also reached the quarter-final in Melbourne last year before losing out to Sharapova.

However, the 24-year-old is confident of producing a better performance this time around.

"It's an unbelievable feeling," said Makarova. "I really like to play here, everything is so perfect. My team did a really nice job.

"Last year I was so surprised [to reach the quarter-finals] and had so may thoughts on my mind. This year, I'm a little bit used to it.

"I think I'll be ready to play a good game."

When asked about the prospect of a rematch with Sharapova, the Moscow native replied: "I think it will be really interesting and I really want to play against her."

Makarova has never been beyond the fourth round of any other Grand Slam.
