Cahill hangs up his boots

Australia's all-time top goalscorer Tim Cahill announced his retirement on Friday, bringing an end to one of the country's greatest football careers.

The 39-year-old -- who scored 50 goals in 108 appearances for the Socceroos and played in four World Cups -- said he will not be looking for another contract following the end of his Indian Super League stint with Jamshedpur.

The former Everton and Millwall attacker, who retired from international football in November, said he is planning a move into coaching.

"No, I'm an old man now in football years," he told Optus Sport television.

"But I'm interested in TV, going to start my A (coaching) licence and spend quality time with my family and chill out for a bit."
