Brazil coach Tite has quashed any chance of Alisson and Fabinho returning early from the international break.
Selecao's final World Cup qualifier against Uruguay kicks off merely 35 hours before Liverpool's clash with Watford.
Klopp had hoped an early release for the duo after Brazil's second game against Colombia could be discussed.
But Tite has put a line through those plans.
Speaking to Win Sports, Tite said: "There was never that possibility [of an early return to England].
"They were called up for the three games."
