Southampton goalkeeper Alex McCarthy has revealed manager Ralph Hasenhuttl has emphasised their work off the ball.
Saints face Arsenal later today.
"He's gone through the way they press, what they do when they have got the ball, without the ball, everything. Everything's clear and we all understand what we are doing and reading off the same page," McCarthy said.
"Everyone's just pressing, pressing, pressing, once you lose the ball. And when we regain the ball, instead of turning round and playing it back, having that confidence to play forward and bring everyone up the pitch so we're a lot more attacking.
"The thing with the boys pressing a lot higher and with more intensity, hopefully I'll have a little bit less work to do!"
