This is why Lambiase did not work with Verstappen in FP1 Imola

Gianpiero Lambiase, Max Verstappen's race engineer, could not be heard on the Dutchman's team radio during the first free practice session in Imola. Instead, Verstappen was accompanied by performance engineer Tom Hart.

The familiar voice of 'GP' could not be heard on Verstappen's team radio during the first practice session at Imola. Lambiase was replaced for this session by performance engineer Tom Hart, who could also previously be heard on the team radio during FP2 in Abu Dhabi last year.

The reason for the temporary change was to allow Hart to get used to Lambiase's work, with the aim of better cooperation between the two. Hart could be heard on the team radio several times during the session as Verstappen struggled with the balance, ultimately failing to get beyond a fifth time after two off-track excursions.

The reigning world champion was unhappy with the feeling in his RB20 and reported problems with grip and his brakes. It was clear that the setup of his Formula 1 car was still far from ideal, something the team would try to solve for the second free practice session.
