But Brazil's Massa vowed on Thursday at Ferrari's annual winter retreat in the Alps that he will give the McLaren driver Hamilton another big fight.

Madonna di Campiglio, Italy - Ferrari team principal Stefano Domenicali strongly criticised Wednesday the introduction of the new kinetic energy recovery system
(KERS) to Formula One for the 2009 season as a waste of money.

"It's throwing money out the window," Domenicali said at a Ferrari media meeting in Madonna di Campiglio.

Ferrari tested their car's KERS system for the first time on Monday at the Mugello circuit in Tuscany but Domenicali said that the current global financial crisis meant that it was the wrong time to introduce such a costly system.

"However, Formula One will come out stronger from the crisis," added Domenicali.
