Tech 3 boss Herve Poncharal believes that an 'upset' James Toseland will be pushing all-out to beat his best MotoGP result during his final four rides.

On Thursday it was confirmed that Toseland will be replaced by Ben Spies at Tech 3 Yamaha for 2010 - with the Englishman returning to World Superbike by taking the factory Yamaha seat vacated by Spies.

"I like James. We believed a lot, Yamaha and myself, in James' potential when we decided to take him to MotoGP," began Poncharal. "We have to remember that in his first ever grand prix he qualified second on the grid and he had some good races - Australia last year and Assen this year for example - but altogether it was frustrating. For him and for us.

"But James is a good person. He has been very professional and very dedicated. I want to thank him for this. It is always difficult to lose someone that you enjoy a great relationship with, but MotoGP is the ultimate class in motorcycling and I think Ben coming was the priority.

"But I'm really pleased that James will stay with the Yamaha family and have, I think, the best bike in next year's World Superbike Championship. I wish him good luck.

"We still have another four races to go and I know he is very upset not to have done better than sixth, so he will be pushing to improve his best MotoGP race position before he leaves the MotoGP world."

Toseland, who arrived in MotoGP with Tech 3 as a reigning double WSBK champion at the start of 2008, has taken a best finish of sixth no less than nine times during 31 grand prix races.
