Jurgen Klopp hinted that Liverpool will be without Roberto Firmino, Alisson and Fabinho for the trip to Leeds United on Sunday.
Firmino misses out through a hamstring injury sustained against Chelsea but the availability of Alisson and Fabinho remains in doubt after Brazil called on FIFA to suspend the players from playing this weekend.
Brazil requested the governing body to take action after the Premier League clubs agreed to not let their players travel to South America, amid quarantining fears on their return subsequently causing them to miss fixtures.
When asked for an update on the situation, Klopp told reporters at Friday's pre-match news conference: "I know Bobby [Firmino] will not be available because of injury. About the rest, no.
"It’s a really difficult situation and really tricky for all the clubs and players, especially.
"We should not forget the players wanted to play, the clubs wanted to let players go but it was not possible.
"It looks like the real punishment is on the players because they can't play and, of course, the clubs as well.
"That's really not okay, we didn't decide that the players could not go.
"Brazil played 1.30am this morning [UK] time, they won all 3 games and still there is a complaint.
"Before the last break I met [Arsene] Wenger and he showed me World Cup plans. In that moment I got the message from our guys 'no exemptions from government for our players'.
"Now we have that situation, we still don't know who we can line-up at the weekend.
"I've no idea when I can expect a solution, we will see. I don't know what moment I have to make the decision. I want to play them on Sunday but we will see."
Klopp's side travel to Elland Road on the second-longest unbeaten run in England's top four tiers (13), also winning seven of their last eight Premier League matches on the road.
Leeds are winless in their last eight top-flight meetings with the Reds, though they held Liverpool to a 1-1 draw at Elland Road last season.
