Brendan Rodgers insists there is still plenty of room for improvement from his Leicester City side.
The Foxes have kicked off their Premier League campaign with seven points from three games.
"I'll be happy for the boys to go away on international duty because they can play and add to their fitness," Rodgers said.
"It's always difficult in this first three-to-five games. You're always searching [for fitness]. If you look at the likes of Harvey [Barnes], he's still trying to get up to speed fitness-wise.
"They'll have a few days off, but then we'll be really excited about the month ahead after it. We've gone some great games and we're into European football again.
"One or two of the other lads too. It is what it is. The boys will work hard, the guys who will stay. They'll have a few days off as well, but then we'll be really excited about the month ahead after it. We've got some great games and we're into European football again.
"It's just about patience and time and work. That will improve as the season goes on."
