Lewis Hamilton finished way off the time of his team-mate during the final practice session at the Singapore Grand Prix, as Lando Norris thrashed his championship rivals.
Hamilton was around eight tenths behind George Russell, who managed to put his Mercedes up in second despite the team's poor Friday performance.
Norris, meanwhile, was almost half a second up on the rest of the field, giving McLaren real confidence that they have the better of their championship rivals heading into qualifying.
Max Verstappen improved on his Friday performance to put his Red Bull up in fourth, but was nine tenths behind the time of his championship rival Norris.
His team-mate Sergio Perez, meanwhile, could only put his RB20 in 15th, once again suggesting Red Bull may lose yet more ground in the constructors' championship fight.
In a bizarre start to the session, a lizard caused a brief pause to running, as it decided to roam around the Marina Bay Circuit, causing a red flag as stewards raced to try and catch it.
