Regarding the new upgrade, Verstappen said "I don't feel a massive difference yet. If I did, I would tell you."

However he did express a vote of confidence in his teammate for today's race, with Ricciardo lining up fourth on the grid.

"I’m sure Daniel can do it," Verstappen said. "I'm in the back, so..."
