Liverpool manager Jurgen Klopp is wary of their resurgence being halted by one bad performance.
The German, who wore a Beatles t-shirt to his news conference on Friday, presided over the Merseysiders' Europa League triumph over arch-rivals Manchester United just over 12 hours earlier and remained in good spirits.
He warned, however, that the confidence gained from their recent displays - their only defeats in the last 10 games have been in cup competitions to Manchester City and West Ham - can disappear easily.
Speaking ahead of Sunday's trip to Southampton, he said: "The problem with confidence is that it's a little flower and if you step on it it's gone in a second.
"But it's not only about confidence, it's about feeling more and more trust in our way of playing.
"Everything is prepared for a good game. Southampton are a really good side and if we want to win we have to be really good.
"Hopefully we have a good squad, a good line-up for Southampton because it was intense yesterday."
Liverpool impressed in the 1-1 draw at Old Trafford which completed a 3-1 aggregate triumph, their counter-attacking style resulting in plenty of chances which they were unable to convert.
Klopp added: "We try to do our best and get the right result. We have to carry on this way. To play like this, a possession team with a high rhythm and intensive style, then we can get a few points.
"If we collect enough we will have to see what will happen. We have to win our games and then see."
