The former Formula One world champion Lewis Hamilton has taken a swipe at critics, including former Formula One drivers, who'd warned his move to Mercedes was a mistake.
Having finished fifth in the season-opening grand prix in Melbourne at the weekend Hamilton says it's nice to prove people wrong.
Hamilton had qualified third on the grid.
Hamilton's decision to leave McLaren, perennial championship contenders who gave him his F1 debut in 2007, for a Mercedes team who were largely off the pace last year was widely considered a gamble.
However Mercedes have looked far more competitive in testing and in practice while the new McLaren has had a troubled start with Britain's Jenson Button and Mexican Sergio Perez ninth and 11th respectively on Sunday.
