Cousins swapped New Orleans Pelicans for the Warriors this summer but has yet to feature for his new side because of a long-term injury.
The 28-year-old is expected to make his return over the coming weeks and should be fully fit for the Lakers’ trip north on Boxing Day.
The two teams clashed twice in pre-season with the Lakers coming out on top on both occasions.
However, Luke Walton’s side have had a difficult start to the season with just five wins, compared to the Warriors’ 10.
But Cousins fears with LeBron James in their ranks there is always a likelihood of an upset.
“They got the best player in the world,” Cousins told heavy.com.
They’ve got a chance [of beating the Warriors].
“We’ll see what happens when the ball goes up.”
Cousins also spoke highly of his new team-mates for how well they click together, which has shown by winning three Championships in the last four years.
“It’s a team full of high IQs,” he added.
“I believe everyone on our team has a very high IQ when it comes to the game of basketball.
“All of us know how to play the game of basketball. We got guys with the same characteristics that – it’s like play-doh.
“You can mould them into whatever you want them to be.”
The Lakers return to action against Sacramento Kings tonight, while the Warriors take on Brooklyn Nets.
