Southampton captain James Ward-Prowse hailed victory over Leicester City.
Carlos Alcaraz struck the winner for Saints after Ward-Prowse had his penalty saved.
He later said: "Huge result. It has been a tough couple of weeks with a few home truths. You saw a turning point in our season.
"I'd rather a free-kick [than a penalty], sometimes you score them, sometimes you don't. Fair play to the keeper, but three points is better than any goal you can score.
"Midweek [the FA Cup defeat by Grimsby] was never near the standard we should be producing. It is the sign of a good group that we can turn it around. We got let off the hook at times today."
