Bottas and his teammate Lewis Hamilton started the race fifth and second respectively but finished the race under the lights in fourth and fifth after they got their strategy wrong, allowing Ferrari to win for the third race in a row.
At a track like Singapore, where it is so hard to overtake Bottas explained what Mercedes needed to make the necessary overtakes.
"The car felt quick today, but you need a pace delta of almost two seconds to overtake in Singapore, so we couldn’t really attack the cars ahead," Bottas said.
"We have rules of engagement for our pit stops as we don’t want to use them to swap position between our cars. The car ahead always gets the priority; so if the car behind stops early and undercuts, we will make sure that the other car still ends up in front."
At a track, they were massive favourites for, Bottas admitted Ferrari can't be happy with their results at the Marina Bay Street Circuit.
“We can’t be happy with our results this weekend, so we will analyse and review everything diligently as there’s a lot that we can learn from qualifying and the race."
