Brentford boss Thomas Frank says it's important they keep their feet on the ground after last week's shock victory over Arsenal.
The Bees this weekend travel to Crystal Palace.
Frank said, "The victory over Arsenal gives us a lot of confidence, but the Premier League is more than Fridays in the spotlight at our new stadium, where everything is boiling. We must be able to perform in different environments and show that we can be consistent.
"It's going to be really hard. They're going to be over us from the first minute. It's a tough team to break down, but we have faith in ourselves.
"We will go there and do our best to be brave again."
