Aston Martin team principal Mike Krack has claimed that the team are struggling to predict their position relative to their rivals ahead of the British Grand Prix.
The Silverstone-based team travelled to Bahrain for the season opener as the clear second-fastest team on the grid behind Red Bull, but the battle for P2 in the constructor standings is starting to hot up.
Ferrari were the second-fastest on track in Austria, while Mercedes had shown promise in Montreal but struggled for pace throughout the weekend at Spielberg.
Even more concerning for Aston Martin could be the rise of McLaren, who took a giant leap forward at the Austrian Grand Prix with Lando Norris recording a P4 finish.
