Chelsea scored four past Frasier Forster as the Blues defeated the Saints 4-2 to claim all three points at Stamford Bridge.
Southampton captain Steven Davis admitted Chelsea were the better side in terms of finishing and hailed the fighting spirit of his team.
“Chelsea were more clinical than us,” he admitted the game.
“We worked hard to get back into the game and the timing of the second goal was bad for us. Unfortunately it wasn’t to be.
“They are top of the league for a reason. We want more than just getting 40 points. We don’t want our season to fizzle out.”
