Andy Murray is going for Australian Open glory today as he aims for his third grand slam title.
The Scot will have to overcome Serbian world number one Novak Djokovic in the men's singles final if he is to go one step further than his previous Australian outings and lift the trophy in Melbourne.
Victory Down Under would see the British number one achieve a special family double.
His brother Jamie yesterday became the first Briton to win the Australian Open men's doubles title in more than 80 years.
Jamie secured his first doubles grand slam trophy when he and partner Bruno Soares came from behind to beat Canada's Daniel Nestor and Czech Radek Stepanek in the final.
Andy stayed up late into the night to watch his older brother's triumph - but was urged to head back to bed.
In his on-court speech, an emotional Jamie told his brother: "Andy you should be in bed, I don't know why you're here taking photos."
A win for Andy would form the second part of a remarkable Scottish treble at this year's tournament after Gordon Reid won the wheelchair singles on Saturday.
The 24-year-old from Alexandria, West Dunbartonshire, edged out Belgium's Joachim Gerard to secure his first grand slam singles title.
Victory for Andy would see him add to his 2013 Wimbledon and 2012 US Open grand slam titles.
He also won Olympic gold in 2012 and recently rounded off 2015 by steering Great Britain to its first Davis Cup title in almost 80 years.
Murray knows to expect a long haul if he is to overcome Djokovic and clinch the Australian title for the first time in his career.
He has only beaten the Serbian once in their last 11 meetings, but will be hungrier than ever to reverse his current streak of four consecutive defeats in grand slam finals.
Speaking before the match, he said: "The most important thing for me is to sustain my level for long enough, not just for one set here or there, a few games here or there.
"I need to do it for a very long period if I want to get the win."
