While it's far from ideal to have to work pre-season around the varying player return dates following a summer international tournament, it does often mean the younger players get a chance to play for the first team.
That has certainly been the case for Real Madrid so far this summer.
Against Inter Milan in their first pre-season friendly, a host of young players were handed minutes, with Lucas maintaining his place for the Roma match.
The forward demonstrated his vision to set up Gareth Bale for an early chance, while only Lukasz Skorupski's shrewd keeping prevented him getting his name on the scoresheet.
Raul de Tomas, a second half substitute, was also unlucky not to register a goal, although he showed few nerves when it came to getting shots away.
There were also appearances for Diego Llorente, Omar Mascarell, Ruben Sobrino and Alvaro Medran.
"The youngsters were good," Alvaro Arbeloa told Madrid's official website.
Meanwhile, the only three players to complete the match were three players who are still, relatively speaking, youngsters as well: Dani Carvajal, Asier Illarramendi and Isco.
The trio were signed last summer as Madrid looked to usher in a Spanish era at the club, although with a change in direction during this transfer window—see the signings of James and Kroos—Isco and Illarramendi, at least, are going to have to fight for their minutes this season.
Ancelotti's giving them plenty of time to show what they can do in pre-season.
