Max Verstappen has ominously suggested Red Bull has improved "everywhere" ahead of the new season.
The Milton Keynes-based outfit cantered to the constructors' championship last season, with 205 points separating it with runner-up Ferrari as Verstappen enjoyed a comfortable 146-point margin to Charles Leclerc.
Red Bull unleashed the RB19 for the first time at last week's Bahrain pre-season test and hit the ground running, with Verstappen topping two of his three sessions behind the wheel.
