Sergio Perez says fresh hope has been breathed into Red Bull's title hopes, with the team now confident that their early-season reliability problems are behind them.
Perez and teammate Max Verstappen shared three retirements during the opening three races, dropping plenty of points in the process.
Their issues have allowed Charles Leclerc and Ferrari to build a healthy lead at the top of the standings heading into a home race in Italy.
But, after Verstappen stormed to victory in Saturday's Sprint at Imola, Red Bull approach Sunday's 63-lap race filled with confidence that their reliability woes are now a thing of the past.
"What gives us hope is that all the issues or the reliability problems we've had, we understood them and we were able to fix them," Perez said, speaking to members of the media including RacingNews365.com.
"From now on, hopefully, there are no more surprises. Something unexpected can happen still, but we feel like we've [got] on top of them."
