They also appeared to be engaged in a conversation as they walked past the Scuderia Ferrari team hospitality center.Shifting attention to the on-track action, the Friday session at the Italian Grand Prix proved to be relatively impressive for both Carlos Sainz and Charles Leclerc. However, the same cannot be said of Pierre Gasly.While Sainz finished both FP1 and FP2 in third place, Leclerc, on his part, maintained a consistent second place for his Ferrari team during both sessions. Gasly also followed in the trend of the consistent results, albeit at the wrong end of the grid. The Alpine F1 team driver mustered up two 18th-place finishes across both Free Practice sessions.With the first day of the Italian Grand Prix weekend out of the way, the trio will now shift their focus to the Saturday session, which includes qualifying for the Sunday race.The three drivers boast relatively fond memories racing at the circuit, with Gasly recording his only F1 win to date during the 2020 edition. Leclerc also claimed victory at Monza in 2019 and 2024. For Sainz, his best result remains his podium finish during the 2023 edition of the race.
