Tennis: Hewitt gets advice on how to regain the fire

Australia's former head swimming coach Don Talbot has offered to help Lleyton Hewitt rediscover his aggression for tennis.

Talbot has contacted Hewitt's camp offering advice on how the former world No.1 one can return to the top.

Talbot says he believes Hewitt has curbed his aggression because of constant criticism of his on-court behaviour, and should stick to his instincts.

"I just said, 'I'm no expert on tennis, but I know how to win'," Talbot told Sydney's Daily Telegraph.

Hewitt has not won a Grand Slam since the US Open in 2001 and has slipped to 18th in the world rankings.
