Brett Michael Emerton (born 22 February 1979 in Sydney, Australia) is an Australian footballer who is currently playing for Blackburn Rovers in the English Premier League and the Australia national football team.

The phenomenally fit wide player has cemented himself as a first choice member of Pim Verbeek's Australia team, be it as a wing back or in the midfield. The Blackburn stalwart provides an unmatched physical presence on the pitch, combining size, pace and strength with unwavering energy levels and underrated technique. Having made his debut as a youngster, he is one of the highest-capped Socceroos and could conceivably amass the most appearances before retirement.

Emerton launched himself on the path to success by transferring from Sydney Olympic to Dutch giants Feyenoord in 2000, after captaining the Olyroos at the Sydney Olympics. After three seasons in the Netherlands he secured a dream move to the Premier League, joining Blackburn for £2.2 million, the club he has been loyal to ever since. A swashbuckling right winger in his younger days, Emerton has been used in various midfield slots and more defensive roles as his career has developed. Australia's 2006 World Cup mentor Guus Hiddink saw Emerton's fitness and power as valuable assets, and converted him to a full back with a license to burst forward when the opportunity arose.

Post Germany 2006 has seen Emerton revert back to a more attacking role for Australia, partly due to Luke Wilkshire's growth into the right back position and also because of the Socceroos' struggling final third. Emerton's first instinct is to drive at the opposition and make something happen, which draws the occasional groan from Australian supporters if he loses the ball or ignores an easier option. But the flyer is most notable when he is absent, such as in Australia's round of 16 exit at the hands of Italy, when the fateful last-ditch raid by the Italians down the right flank of Emerton - who was suspended - led to the deciding penalty that sent Australia packing
