Mercedes deputy technical director Simone Resta has warned that the team will face a "more intense" battle to clinch Formula 1 title glory when the championship resumes in Zandvoort. Ahead of the summer shutdown, Mercedes' dominant streak had well and truly come to an end, with five different drivers tasting victory in the races leading up to the August break. Such is the team's single-lap pace, that Hungary marked the first time a driver not in a Mercedes had taken pole position this term. "The pressure increases on the teams that are leading, but equally it increases on the teams trying to catch up. "It's where teams demonstrate whether they can handle the pressure and continue performing when the stakes become higher.
