Gibernau admits a lot of work needed

The 35-year-old Spaniard will return to racing next season after leaving MotoGP at the end of 2006.

The Catalan has joined the new Onde 2000 squad, who made their MotoGP track debut yesterday in the first test following the end of the 2008 season.

Gibernau finished two seconds off the pace set by Casey Stoner.

"All the other riders are too fast for me to follow at the moment," Gibernau told the official MotoGP website. "They are all pretty sure of what they are doing, and I'm not yet.

"I'm still in need of learning what I have to do to get this bike fast; I'm not scared, but I've got a lot of respect for what everyone is doing in this championship."

The Spaniard, who had tested for Ducati earlier this year, admitted he was thrilled to be back in action following his decision to leave the sport.

"I was so excited to be back again," he said. "It's been three years since I last rode at Valencia, which is a big gap, but I enjoyed it a lot.

"We're good professionals and have put a very good group together, but we need to work at some tests to see how to work best with each other.

"I'm going to bring all my experience and know-how and try to get us up to speed in the fastest possible way."
