McLaren turn up at the Singapore Grand Prix under pressure after a troubled stretch of races. Team principal Andrea Stella admitted the MCL40 lost performance following the latest updates, and the team owned the problem for a ongoing flaw affecting Lando Norris.

Norris described a straight-line speed deficit as seriously damaging and said he was uncertain the team could address it before Marina Bay.

A tyre strategy call during the Malaysian Grand Prix, which saw Oscar Piastri pitted under controversial conditions, was later called out as an error in judgement. Singapore's narrow, technical layout is considered a poor fit for the MCL40, adding to the pressure on McLaren heading into the race weekend.
