Goalkeeper Artur Boruc believes Southampton are are improving by the day under Mauricio Pochettino.
A solid start to the season got going in earnest on Saturday when Saints left Anfield with a 1-0 win over Liverpool.
Brendan Rodgers' Reds had come into the game unbeaten in the Barclays Premier League but found no response to Dejan Lovren's 54th minute header and Boruc's impressive form in the away goal.
The Poland goalkeeper helped preserve the points when he turned away Steven Gerrard's goalbound free-kick one-handed and, later on, pushed Victor Moses' effort behind.
It also ensured the 33-year-old claimed his third clean sheet in five outings this season.
Whether he gets the chance to make it four in Tuesday night's Capital One Cup third round match against Bristol City remains to be seen, with Kelvin Davis selected in a much-changed XI for last month's win at Barnsley, but he insists the team are gaining momentum every time they play.
"These kind of games build your confidence, both at the back and at the front," he told Saints Player.
"To win at Anfield is a big thing for us, and hopefully we'll keep that going. This shows how good a team we are.
"We're getting stronger. Every single game is going to be a big one for us, and we've got a couple of new players in the team now so we're going to get even better."
Boruc was less keen to talk up his own contribution to the Liverpool success, but admitted that another shutout was important.
"That's my job - that's what I should do in every single game," Boruc said.
"I'm quite pleased with my performance, especially with the clean sheet, and I'm really, really pleased with our performance at the back.
"We've kept clean sheets in three of the five (Barclays Premier League) games, which is a good thing for us."
Lovren is another who could be offered a chance to rest against the visiting Sky Bet League One side on Tuesday, but he was also looking forward rather than back after leaving Anfield.
"I think I have played some good games and I did well (against Liverpool) but I can do much better," he added.
"Every time it is a big moment if you score a goal, especially at Anfield but the goal is not important, what is important is three points.
"We deserved this win and we really deserved it.
"Hopefully we will do the same and win the next game."
Jack Cork, Steven Davis, Jos Hooiveld, Gaston Ramirez and Maya Yoshida are among those who will hoping to step up to the starting side against Bristol City.
Bristol City will be without defender James O'Connor.
The Robins have yet to enjoy a league victory this season but have found their form in the cups with victories over Gillingham, Bristol Rovers and Crystal Palace.
But they travel to St Mary's without O'Connor who will have a scan on an injury on Wednesday, one which is expected to sideline him for months.
Louis Carey has a bug and will not feature while Aden Flint and Marvin Elliott are carrying knocks. Head coach Sean O'Driscoll is unlikely to make many unforced changes apart from Marlon Harewood and Elliot Parish, who have featured in their cup victories.
