Sebastian Vettel's new-found error-prone nature may be impacted by the "pressure-cooker environment" at Ferrari, according to his former boss Christian Horner. The Red Bull team principal says Vettel's issues are unrecognisable from his title-laden time with his former employers.
Vettel's 2018 title challenge fizzled out amid a string of on-track errors, perhaps sparked by his spin off the circuit and into the gravel at the German Grand Prix which cost him a win and handed the championship lead to Lewis Hamilton.
Further errors have come in 2019, as Ferrari have struggled to keep pace with Mercedes, and his mistake while leading in Canada would have consequences as he was ultimately penalised for his return to the track, which saw his win handed to Hamilton once again.
Such an error seem alien from his Red Bull days, which were often characterised by dominant wins from pole position, something not lost on Horner.
Horner told PA Sport: "With us, Sebastian was like a metronome when he was in the lead of a grand prix. He was always so strong in that position.
