Jurgen Klopp is undecided whether his returning trio of stars will face Manchester City on Sunday.
Alisson, Mohamed Salah and Roberto Firmino all featured in preseason for the first time in Wednesday's 3-1 victory over Lyon, with the latter scoring the Reds' first goal.
But Klopp isn't sure the trio will be ready to face City at Wembley in the Community Shield.
He told the club's website: "I don't know yet in the moment, so that's how it is. We have to see. I don't say 100 per cent not, there's a chance that they will play, yes.
"They will be involved whenever, from the start, maybe we cannot make these changes like today after half an hour or whatever, that's maybe not possible in that game so we have to see.
"We have to see how they react tomorrow, now training is not the highest intensity anymore, now training is about the detail [and] we really need to prepare the game.
"Man City is different to all other games that you play you have to play a pre-season game against Man City to prepare for Man City and we didn't do that!
"We need to adapt to that but all good. Today was from a physical point of view very, very important for all the lads and from a psychological point of view of course as well. We are all human beings and losing football games we never get used to, so I'm really happy that we could change that today."
