Ralph Hasenhuttl insists he will not accept complacency as Southampton seek to end their long wait for successive Premier League wins.
Saints, who climbed out of the drop zone by upsetting Arsenal last weekend, have not won back-to-back top-flight fixtures since April 2017.
They travel to second-bottom Huddersfield on Saturday, for a fixture manager Hasenhuttl has described as a "six-pointer".
And the Austrian is adamant he will not allow his players to rest on their laurels in their attempts to move clear of relegation danger.
"I think the last time we had two consecutive wins was a long time ago. I heard about that," said Hasenhuttl.
"But you can be sure as long as I am manager here that if I have the feeling that one guy makes one step less I will tell him.
"And when I tell him, I am sure he will immediately improve, that's for sure."
Before beating Unai Emery's Gunners, Hasenhuttl lost at Cardiff in his first match since replacing the sacked Mark Hughes.
He is keen for his players to prove they have learnt lessons from the setback in south Wales.
"Against Arsenal we were not the favourite and now it's about a 50-50 game in Huddersfield," said Hasenhuttl.
"We had such a game against Cardiff and we want to show now we are one step further in our development."
He added: "We are sure it will be an enormously hard game we are facing but I think if we have the same passion and the same character and mentality (as last week) – and we will need it against Huddersfield – then we can win there."
Southampton will have defenders Jack Stephens and Cedric Soares and midfielder Mario Lemina back in contention in West Yorkshire following injuries.
Left-back Ryan Bertrand, who recently underwent a back operation, is likely to be the only absentee.
The Terriers clash is the first of four top-flight games in just 12 days for Saints during a busy festive period.
But former RB Leipzig boss Hasenhuttl, who was accustomed to a winter break in Germany, is not considering rotating his squad just yet.
He said: "I am not in the situation that I change everything because one or the other players is a little bit tired. That is not in my mind at the moment.
"Sure if you play Thursday, Sunday and Wednesday – I think it is West Ham, Man City and Chelsea – it can be that with our intensive kind of football it's not possible to play three times in a row.
"Therefore we will need the whole squad, and that's what I am telling the guys."
