Wolff: Mercedes "must stay open-minded" and evaluate Ferrari

The Mercedes front wing is completely different from that on the Ferrari car. Mercedes admitted earlier in the week that it would take months if they needed to change to the Ferrari wing.

However, after week one in Melbourne, you'd think that Mercedes have opted for the correct design. But Wolff insists the team must continue to evaluate the work carried out by other teams.

"I think you need to evaluate all the various philosophies that are out there," Wolff told motorsport.com.
