Ralph Hasenhüttl is hoping to see a reaction from his team to the opening-day defeat at Burnley when they host Liverpool on Saturday, following an intense week at Staplewood.
The Saints boss cancelled a scheduled day off for the players on Monday in order to hold meetings with them, in the aftermath of the 3-0 loss at Turf Moor, before heading back out onto the training pitch from Tuesday.
Hasenhüttl has been pleased with the preparations for the clash with the Champions League winners and Premier League runners-up, and wants to see that work come to fruition at St Mary's this weekend.
"Like always, we look on the last game and work on a few weaknesses we had, but also focus on the game that is coming now," he said. "It is a different game, a different opponent, and not with less quality!
"It's been an interesting, intense week. We had good sessions and also a few other things we have to speak about. We took the time to prepare in a good way I hope, but then we must show this.
"Like always against these big teams, we must not give them too many chances, because they have so much quality they don't need a lot to score. And, finally, to focus on the moments when we have the ball, and when we win the ball what we do there, and know that we also have the quality to score against Liverpool.
"We showed that last season, so it's about giving a really, really good performance. A good, committed performance, defensively well-organised and offensively with the right decisions in the right moments."
Saints did much of that last season when they hosted Liverpool at St Mary's, taking the lead and going into the final ten minutes of the game level at 1-1, before the Reds scored twice late on to win.
ralph hasenhüttli want to see a reaction from the team that is really believing in what they are doing.
"For 80 minutes it was a good example, but finally you see it's not enough," said Hasenhüttl. "Against these teams you must be convinced that you can do it. Nearly surprising them is not enough.
"When you want to surprise them you must be very clinical when you have a chance. Last season we had 80 very good minutes against this team, but then they showed us in the last ten minutes what you can win with mentality.
"In this part I think we must develop ourselves from last week. That was the biggest weakness last weekend, and on Saturday I want to see a reaction from the team that is really believing in what they are doing and stay on the track until the last minute, and if we are like that then we are not so easy to beat.
"We have worked on every part of our game and I'm sure we can also create chances for us, and finally we have the players to score also against Liverpool."
