Gerhard Berger believes its early days still, with no compelling reason to declare Ferrari the favourite to win the 2017 title.
A ten-time Grand Prix winner who enjoyed a double stint with Ferrari from 1987 to 1989 and the again from 1993 to 1995, Berger feels that Mercedes still has the upper hand over the Scuderia despite Italian squad's win in Melbourne.
"After just one race on a city circuit such as Melbourne, it's always difficult to assess the pecking order properly," he told Austrian broadcaster Servus TV.
"What I say is that we have to wait three races to get a clearer picture," Berger added.
"But for me it is clear that Ferrari has made a big leap forward, which surprised me.
"I currently see Mercedes ahead in qualifying, and maybe less in the race. But this was more to do with circumstances. I believe Mercedes has maintained a lead.
"But of course, as fans we all hope that the top three teams will all be together, and then we will watch a great world championship."
"I'm sorry, but what Lewis said is of course nonsense," said Berger.
"In Formula 1 there are a number of drivers like Ricciardo, Verstappen and Rosberg who are all at the top, top level. It's not just about Lewis and Sebastian," he said.
