McLaren head into the Singapore Grand Prix in a difficult position after a difficult stretch of races. Team principal Andrea Stella admitted the MCL40 lost performance following the latest updates, and the team owned the problem for a recurring problem affecting Lando Norris.

Norris called out a straight-line speed deficit as a real concern and said he was uncertain the team could fix it before Marina Bay.

A tyre strategy call during the Malaysian Grand Prix, which saw Oscar Piastri pitted under disputed circumstances, was later called out as an incorrect judgement. Singapore's slow and unforgiving street track is considered a weak circuit for the current car, heaping more stress on McLaren as they prepare for the race weekend.
