Chelsea striker Hernan Crespo is desperate to show his true form for Argentina at the World Cup in Germany.

"I want to show more than what I did in the last two World Cups," said 30-year-old Crespo, who inherited the number nine shirt worn by Gabriel Batistuta. "In 1998, it was my first time, there was a bit of pressure, everything was new and we had some problems with press.

"And again in 2002, unfortunately, we didn't have enough time as we came back home after the group stage. This World Cup will be different for me. After those experiences, I can enjoy more the fact of belonging to the national team and I think I'll be able to play a good World Cup."
