Wolff adamant Mercedes still the 'challengers' after Melbourne

"Claiming the maximum 44 points race from the first race was a fantastic result, we could not have asked for a better start to the season,” Wolff said. 

“But the fight has only just begun: Ferrari will try everything they can to hit back and Melbourne showed that Red Bull will have something to say in the fight, too. 

“We've seen the potential of Ferrari's package in Barcelona, so we expect them to come back strong in Bahrain, with Red Bull in the mix as well. We will see a very different race in Bahrain.”
