Ducati team manager Vittoriano Guareschi hopes that this weekend's Valencia MotoGP finale will see 'positive feelings' as well as sadness at the tragic loss of Marco Simoncelli.

Fellow Italian Guareschi attended the funeral of the much-missed Honda Gresini rider last week and admits it will be a tough weekend.

"The Valencia Grand Prix will have a different atmosphere than normal because we've been thinking about Marco since Malaysia," said Guareschi.

"He'll be with us in Spain and beyond, but I think there will also be positive feelings in the paddock, because for Marco, racing equalled happiness, which is a concept that I understand very well.

"That being the case, we'll do what we always have and do our best to provide Vale and Nicky with what they need to have a nice race. Then on Tuesday and Wednesday we'll take part in the test, and we'll see the new-generation [1000cc] bikes together for the first time."

Rossi and Tech 3's Colin Edwards were caught up in Simoncelli's fatal accident, on lap 2 of the previous Sepang round.
