Marko gives a prediction on how many races Red Bull will win

Helmut Marko doesn't lack any confidence as Red Bull's first season with Honda edges closer and closer. He is certain we'll see Red Bull overalls on the top step of the podium at least five times in 2019.

At the end of last season, Marko came out and said Red Bull will make Max Verstappen the youngest ever world champion. The 75-year-old isn't slowing down on the predictions.

"We will win at least five races. I believe we also have a chance at the world championship," Marko told Germany's motorsport magazine.

On the whole, Barcelona testing looked positive for Red Bull. Other than rumours around engine vibrations on day one, limited problems with Honda arose. However, their new recruit, Gasly, had a couple of damaging crashes.

"Especially the second crash was completely unnecessary. It threw our entire test programme overboard. Gasly must show more discipline. We ran out of spares, so Verstappen could hardly drive on the last day. We couldn't test the parts in the complete package, so of course we're not sure [if they work]," Marko added.
