Bottas dominated the first two qualifying sessions but was then pipped to pole position by team-mate Hamilton in Q3.
Mercedes have locked out the front row as they hunt a sixth straight one-two finish.
But Bottas has bigger plans as he hope to attack Hamilton at the front of the pack.
However, there are so few overtaking opportunities on the street circuit and that will make his afternoon extremely tricky.
“It is better this morning than after qualifying,” Bottas said.
“We are going to be on form in the race. I know overtaking is difficult here but we will look for the opportunities.
“We have a strong package as a team and that is always very good to see.”
Bottas may be able to take solace from the fact Hamilton has a poor record in Monaco.
The Brit has only won two of his 12 outings at the most famous race of all.
But Hamilton is hoping to improve his form in Monaco this year.
“You know, this race – as you’ve seen in the previous years – lots of things get thrown at you so we’ve just got to stay on our toes,” Hamilton said.
“But I honestly feel that were the best prepared, we’ve had a really solid weekend of preparation.
“We’ve had good years of experience too but that doesn’t mean that there are unknowns ahead but we’ll face it together.”
Meanwhile, Red Bull’s Max Verstappen is hoping to put pressure on the Mercedes pair from third place.
“I think we are competitive but it’s very hard to pass,” he said.
“We’ll give it everything we’ve got.”
