Southampton boss Ralph Hasenhuttl is ready to go with a back four against Chelsea tonight.
The Saints have used a three-man backline in recent seasons but Hasenhuttl looks likely to go with a more traditional rearguard for the visit of the Blues.
He told the pre-match press conference: "I think it seems that we are more comfortable with the back four.
"We have more players up front and it helps us, especially to create good chances.
"It's always helpful when you have more quantity up front. Sure, you also need quality in moments but one player more gives you more chances.
"It's the reason why we are not struggling to create chances at the moment and we are not struggling to defend. This is good to see."
