Everton star Tim Cahill is adamant that he is a much better player now than he was four years ago. The Australia international insists he has improved in every aspect of the game in an ominous warning to the Socceroos' Group D World Cup rivals Germany, Ghana and Serbia.

In the May edition of FourFourTwo magazine, Cahill stated that he felt much better in 2010 and had grown in stature since his heroics at Germany 2006.

"Now I am a fitter, stronger and better player than ever before, 100% better than four years ago," said Cahill. "It is weird looking back to Germany because I was really excited about it and just looking for new experiences, but I have changed a lot since then.

"I feel powerful, and more confident than ever, I know I can run over 12 kilometres in every game, I know I can mix it with the best defenders in the world, I have the ability and strength. The power I feel inside my body is there because of the way I have looked after myself, and the way I train."
