Red Bull reveals checklist to help Verstappen battle for the biggest prizes at Spa

Red Bull Racing was one of the surprises on the opening day of the Belgian Grand Prix weekend at Spa-Francorchamps. Max Verstappen topped the timesheets in FP1 ahead of the two Ferrari drivers before backing it up with another top-three finish in FP2.

"Promising start to the weekend for us today," GP acknowledged when reacting to the Belgian GP's first day on social media.

Both Verstappen and Isack Hadjar received new power unit components for the Belgian Grand Prix weekend. As a result, Hadjar will start Sunday's race from the back of the grid.

Verstappen said his car was in a "good window" after the opening day at Spa-Francorchamps. However, Lambiase highlighted that Red Bull still has work to do to fine-tune the Dutchman's car if it wants to fight for pole position on Saturday and victory on Sunday.

GP continued: "On top of that obviously we're not quite where we want to be either with Max missing a few tenths so again a little bit of focus for Max on dialing in some front end.

"And then yeah, finally another energy-poor track similar to Silverstone so really going through that with a fine tooth comb, trying to understand where the sensitivities lie and how it there is any way to drive the car or drive the battery in a way that is more performance optimum," Lambiase concluded.
