Juan Cala was the unlikely hero at St Mary's, with the centre-back's wondrous 20-yard strike securing the Premier League's worst travellers a vital 1-0 win.
"It is huge," midfielder Whittingham said. "It was a must-win for us and to get three points drags a lot of teams into it and gives us a fighting chance.
"I said before it was a must-win. We felt like if we didn't get three points then it would probably leave us a little bit out in the cold.
"But it was a good result for us against a good Southampton team, so to get three points was unbelievable.
"The last 10 minutes they had so much of the ball and putting it in our box, so it was about how we defended.
"The boys defended really well and we're really happy to get three points."
