West Ham United boss David Moyes insists there were "a lot of positives" from Monday's 3-2 loss to Liverpool.
The result means West Ham are still in the relegation zone with 11 games remaining.
But the spirited display, which saw them lead 2-1 in the second-half, encouraged their manager.
Moyes said: "There were a lot of positives to take. A lot of people thought we were going to sit back, we scored twice and had two other good chances. Mistakes cost us, that's pretty much been the story of our season. We have given the best team in the world a game. We're gutted that we've lost.
"We kept our shape well. Tonight was about getting up the pitch. I think Liverpool were probably a little bit surprised by the chances we created. Southampton is a massive game for us, there are positives to take from the last two games.
"We've got to be men out there and hold on and we could have taken a point now. It wasn't meant to be and we've got to go again now.
"That has to be the standard going into every game. Take it from Liverpool, they're a great attacking team but they also do the defensive work too."
