Jurgen Klopp insists he's not concerned about his forward line heading into the season.
Mohamed Salah and Roberto Firmino are still on holidays with less than two weeks before the Community Shield against Manchester City.
Sadio Mane will return after that match, with the Premier League opener with Norwich City on Friday August 9.
Speaking after Sunday's loss to Sevilla, Klopp said the Reds can handle not having their stars firing in preseason.
He told the club's website: "We will see. How it always is in life, would I wish for a different situation, would I wish to have my whole squad together for the first day? Yes. That last happened around about 12 years ago, so I am really used to players coming back later and we have to do the specific things.
"It is a five-week pre-season until the league starts, but a four-week until we have the first competitive game against Man City. You still have to do the physical work, but we are really in a hurry pretty much to do that. We cannot look on the games we play.
"Again, I come back to that, I know that, I plan the training, I know what we did, I know we're tired, but I still want to win.
"But the boys when they come back, it should be a really short break, so they should be quickly fit at least physically fit and then we have to work together.
"I think it is pretty rare that you play the best football you ever played on the first matchday; there is usually development during the season, but we want to have results from the first matchday and that's what we are working on.
"We didn't a change a lot in the squad. In the moment, Adam Lallana was not there tonight, Nathaniel Clyne was not there, we missed six to eight players in this moment tonight. You fill it up with the kids and that's nice, it's cool, but it is hard for them as well. No, I am not concerned, but I know about the situation."
