World number four Andy Murray is excited by his Australian Open fourth round match against Kazakhstan's Mikhail Kukushkin on Monday.
The Brit edged out Kukushkin 5-7 6-3 6-2 in his first match of the season at Brisbane earlier this month.
"The first six games he was unbelievable - he hardly missed a ball; he was hitting it huge," said Murray.
"He's having the best run at a Grand Slam in his career so I need to play well, but I'm looking forward to it."
The winner of Monday's tie will face either Kei Nishikori or Jo-Wilfried Tsonga in the quarter-finals.
