Southampton manager Ralph Hasenhuttl has just been on speaking to Sky Sports about why he has plumped for tonight's formation.
He said: "It was not only because of the result against Wolves, today we need the defensive balance and the team did it well, so they get another chance.
"Against a powerful team it helps you. It’s a very flexible shape. We tried it against Liverpool and had a chance to take a point, so we’ll try it again against another strong team."
On the threat of Jamie Vardy: "Everybody know he waits for the moment the ball goes beyond the backline.
"It means we must stop the counter-attack at the beginning if possible because it’s not always easy to stop him."
