'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.''
