Liverpool players, Fabinho and Allison, might be forced to miss the Premier League game against Liverpool on Saturday.
Both players are in the Brazil squad to face Uruguay at 1:30 am on Friday UK time, which is just 35 hours away from the Liverpool Watford fixture set for 12:30 pm on Friday.
This means both players are to finish the game against Uruguay then take a flight down to England and join the training session with the rest of the Liverpool squad before kick-off time which is close to impossible.
"I believe that this first match against Watford will be very hard for us," Fabinho said "I don't think we'll play. Neither Alisson nor myself.
"The match against Uruguay will be Friday overnight there (in the United Kingdom) and the match against Watford is at 12:30 pm (Saturday).
"With all of what is involved with travel, I don't know how much time we'll have between one game and the other.
