Andrew Robertson is confident that there is much more to come from Liverpool after grinding out three straight wins.
Liverpool head into the international break having now opened a league season with four-straight victories for the first time since 1990 following Saturday's 2-1 win at Leicester City.
After the international fixtures, Jurgen Klopp's side take on Tottenham Hotspur, Paris Saint-Germain, Chelsea, Napoli and Manchester City all within the space of a month.
"I think there's a lot more [to come]," Robertson told reporters. "The last three games, we've probably not been at our best so we're still a work in progress and if we can keep getting better it'll be exciting to see what can happen.
"We've got a few big games when we come back but I think all the lads are just excited to go away with their international teams now and some get a break and we'll come back and we've obviously got a big game against Tottenham.
"[Against Leicester] we started off really well, I thought first 20 minutes they couldn't quite deal with us and we could have probably been two or three up then.
"But, after that, we struggled a wee bit, I think they pressed a bit higher and we couldn't get our foot on the ball. It was similar to Palace and Brighton last week at Anfield.
"It's important that we win these games and we had some really good things but some not so good things but it's all about the three points -- 12 points from 12, we can't ask for much better."
Robertson, who was named Scotland's captain on Monday, had been part of a Liverpool back four that had not conceded all season until Saturday -- when goalkeeper Alisson was caught out with the ball at his feet against Leicester.
Instead of focussing on Alisson's error, Robertson wants to highlight the Brazilian's crucial interventions that have helped maintain Liverpool's 100-percent win record.
"I think there are a couple of mistakes before then," the left-back said when asked about Alisson's error at the King Power Stadium.
"We maybe could have played the ball in behind maybe two or three times instead of going back. Then he's been put under pressure and obviously tried a Cruyff but it's not quite worked.
"But I think he learned his lesson after that and he wasn't taking any chances. He's a confident lad and even today he made two or three great saves, so we'll concentrate on that and it's only a small blip.
"He's adapting to the Premier League as well, so as long as he keeps making the saves, we'll be happy."
