Southampton face a Brentford side with little to play for on Saturday but striker Rickie Lambert is still cautious.
The south-coast side are leading the race for the second promotion spot in League One on the back of wins over Brighton and Hartlepool, while Brentford's slim play-off hopes came to an end over Easter.
But Lambert warned: "You have to be careful of that.
"Sometimes it can work in your favour when they are not fully focused on the game, but other times it gives the team freedom and they go out and play better without the pressure.
"We've got to approach it in the same way we approached Brighton and Hartlepool."
