Diogo Jota is set to miss Liverpool’s Community Shield clash with Manchester City.
Jota missed Tuesday’s friendly defeat by Manchester United in Bangkok after suffering a relapse of a hamstring injury first picked up on international duty.
The forward sustained the problem in Portugal’s Nations League encounter with Portugal which will now sideline him for the curtain-opener on July 30.
But Jurgen Klopp remains hopeful of Alisson recovering from his own fitness issue to face the Premier League champions at the King Power Stadium.
He said: “Ali, I think, has the chance for City and Diogo not.
“But, again, we prepare a full season so he can train but not like before, so he should not play in the moment.
“Not normal goalkeeper training but he has a pre-season, so he doesn’t lose time. But these kind of things happen.
“The boys have to travel a lot and train and you never know exactly. It’s only little things, nothing serious.
“But we have to be careful because the rest of the season is much longer than the start.”
Liverpool encountered further injury concerns despite returning to winning ways on their pre-season tour against Crystal Palace in Singapore on Friday.
Alex Oxlade-Chamberlain was substituted during the eventual 2-0 victory with a muscle injury while Joe Gomez had missed the game as a precaution.
“Of course it’s very disappointing for us because Oxlade trained all the time really well since the pre-season started,” added Klopp.
“It happened obviously with Ox in the past when it gets more intense and something can happen.
“Now this is just a muscle thing and that’s OK. We had worse situations, so I’m OK with it.
“I don’t know exactly how long it will take but he will be back and then it’s all fine. He is obviously a top-class player and he can help us.”
