Argentina midfielder Pablo Aimar has vowed to force his way back into the Valencia side after failing to convince coach Rafa Benitez that he is worth his place.

"I am sure I will suddenly take off," he said. "When that happens, everybody will see what I can do."

Aimar has struggled to tie down the playmaker berth under Benitez and admitted: "I haven't done particularly well so far.

"But I'm convinced I will come good, like I did at River Plate. Then everybody will see the real Aimar. I am going to be successful here, I have no doubt about that," added the 22-year-old

"It takes time to adapt to football in a different country, but I don't want to use that as an excuse.

"I know that I can do better but I have to patient. I've played some good games, but never had a continued run in the team and that's why I've had a hard time adapting."

Aimar was part of the River side comprising talented young strikers Javier Saviola and Juan Pablo Angel, plus midfielder Ariel Ortega. Together they were known as the Cuatro Fantasticos.

He signed for Valencia from River Plate for around £15 million in January 2001.
