Andy Murray will play Alexander Zverev in the first round of the Australian Open on Tuesday, but who is the teenage prodigy from Germany?
The 28-year-old two-time Grand Slam champion beat Zverev comfortably 6-3 6-4 at the Hopman Cup in Perth last week but has never faced him before in a professional match.
The 18-year-old, measuring 6ft 6 and ranked 83rd in the world, is widely considered one of the game's rising stars.
Last year he beat world No 12 Kevin Anderson in Washington, the destructive South African who knocked Murray out of the US Open and also upset world No 1 Novak Djokovic in a Wimbledon warm-up event at The Boodles.
He also picked up the ATP Star of Tomorrow Award at the season-ending ATP World Tour Finals in London.
"I know him reasonably well," Murray said.
"I practised with him for the first time a couple of years ago. I've seen him play a few matches since then.
"Obviously getting to play him a couple of weeks ago was good. I also practised with him a couple of times during the week in Perth too.
He serves well. For a big guy, he moves pretty well, too. He's obviously improving all the time. It will be a tough match.
"He's a big guy obviously for his age. Of the young guys coming through, he is by far the tallest of them, which has obvious benefits.
"At the age he's at just now he can cause a few issues. He's still filling out his physique but he's got a very good game.
"He serves well. For a big guy, he moves pretty well, too. He's obviously improving all the time. It will be a tough match."
His father Alexander played in the Davis Cup for the Soviet Union before emigrating to Germany and his elder brother Mischa has been in the world's top 100.
Bayern Munich fan Zverev is also trained by Jez Green, who used to work for Andy Murray. He has climbed 87 places from 161 in July 2014 to a high of 74 in June.
Zverev is surely still a year or two away from causing Murray serious problems, but the Scot is a notoriously slow starter so the Hamburg-born player could spring a surprise.
We will bring you all the news, views and reaction from the Australian Open starting on Monday.
