Liverpool boss Jurgen Klopp has called on the UK government to find "some kind of solution" with the Brazilian Federation to prevent another club-versus-country row.
Brazil have named eight Premier League players in their latest World Cup qualifying squad.
"There must be a solution obviously, because we cannot just leave it like this and say it's not a problem. Yes, it is a problem," he said.
"I'm pretty sure the relevant people are working on this. I know they're working on this, but there's nothing decided yet, at least as far as I'm concerned.
"We have a problem when the Brazilians are allowed, or when they go, to the next internationals."
Liverpool are set to travel to Watford on 16 September without Alisson and Fabinho, as Brazil host Uruguay on 15 September.
Klopp added: "I know it's a Liverpool problem and nobody else's problem, and good for Watford.
"But I just don't know how you can do these kind of things where nobody reacts on the schedule. We have two problems. One is the schedule, it was always a problem.
"TV and other guys, the Premier League, say, 'OK, that's how it is, they have to play, let's have a look how they can sort that'.
"Another thing, it's not good for the players or the clubs as well and I hope the government comes up with some kind of solution."
