Australian Open 2016: Andy Murray wary of Alexander Zverev

World number two Andy Murray is aiming for his first Australian Open title, having lost four previous finals

Andy Murray expects German teenager Alexander Zverev to cause him "a few issues" in the Australian Open first round on Tuesday.

Murray beat Zverev, 18, in the Hopman Cup last week and faces him on Margaret Court Arena at about 01:30 GMT.

Zverev, who is 6ft 6in, beat Murray's US Open conqueror, world number 12 Kevin Anderson, in last year's event.

British women's number one Johanna Konta plays Venus Williams on Rod Laver Arena, also at approximately 01:30 GMT.

Murray, 28, will withdraw from the Australian Open if his wife Kim gives birth to their first child during the tournament.

Of Zverev, the world number two said: "He's still filling out his physique but he's got a very good game and he serves well.

"For a big guy, he moves pretty well too. He's obviously improving all the time, so it will be a tough match."

Konta faces childhood heroine Williams

Johanna Konta lost in three sets to Venus Williams in October

British women's number one Johanna Konta, who faces childhood heroine Venus Williams in the first round of the women's singles, says she will not allow sentiment to affect her performance against the seven-time Grand Slam winner.

Konta, 24, played 34-year-old Williams for the first time at Wuhan in October, and exchanged hugs in the locker room with the American eighth seed after her 6-4 3-6 7-5 quarter-final defeat.

"The experience will be different," world number 47 Konta said.

"It was the first time I played her and she was one of the players I grew up watching when I was younger, so it was definitely a different experience to where I'm at now."

Konta is the only Briton left in the women's draw after Heather Watson lost a three-set thriller against Hungary's Timea Babos on Monday.

Who are the other Britons competing in Melbourne?

As well as Murray and Konta, fellow Britons Dan Evans and Aljaz Bedene are on Tuesday's bill.

Evans, who was 772 in the world rankings as recently as May, beat Bjorn Fratangelo 7-5 4-6 6-0 in the final round of qualifying.

The 25-year-old from Birmingham, now ranked 185, faces 18th seed Feliciano Lopez of Spain on court 13 at approximately 01:30 GMT.

"It wasn't nice [to be ranked so low] but it's the sport we play and obviously I've come out the other side, and I am hopefully going up the rankings now," he said.

Slovenia-born Bedene, who switched nationality in March, follows Evans on court 13 when he meets American Steve Johnson.

"I know Johnson plays well," says world number 49 Bedene.

"He hasn't started the season that good, but he has a great serve, a great forehand. But I know his weaknesses and I know that if I play well then I've got a good chance."

Kyle Edmund is already out after he was hampered by cramp before losing 1-6 7-6 (7-4) 4-6 6-3 6-1 to world number 81 Damir Dzumhur.
