Red Bull Racing advisor Helmut Marko believes the team will win “at least five races” in the 2019 Formula 1 season.
Red Bull showed strong form in Barcelona testing last week, though two crashes for Pierre Gasly – which Marko described as "unnecessary" – cost them precious development time and makes it difficult to pinpoint exactly where they are in the pace pecking order.
However, Marko remains confident that RB will enjoy more wins this season, their first with Honda engined, than the three they claimed last year with Renault power.
"Ferrari are favourite," Marko explained in an interview with Germany's Motorsport-Magazin.
"Ferrari were quick as if they had already done a test for a week [beforehand]. We were on the back foot due to Gasly's two accidents and the resulting loss of time.
"We brought things that did not fully develop due to Gasly's crashes. Especially the second crash which was completely unnecessary. [He] must clearly show more discipline!"
Marko added: "We will win at least five races."
However, he admitted that Red Bull need to challenge to a greater degree on the faster tracks and not only on street-style circuits, where their superb downforce and chassis give them an edge.
"The tracks on which we are competitive need to be broader,” Marko said.
When asked to predict where they stand heading to the opening race of the 2019 season in Melbourne next weekend, he replied: "It's hard to say, but we think we're between Ferrari and Mercedes.”
