Arsenal manager Unai Emery believes the club's youngsters have a vital role to play as they strive for success this season.
The Gunners are competing on several fronts, including the Premier League and Europa League.
Squad rotation is essential if they are to maintain form and fitness over a lengthy and gruelling season.
It is why Emery believes the younger players emerging in the squad have vital roles to play.
"We can play better each match. It's one process. Little by little we're using the young players to achieve the performance, giving them confidence and experience in the matches," Emery told reporters.
"For example, Bukayo Saka is improving, helping us and taking a good performance. I know he needs to break more steps ahead in his improvement. Other players are the same.
"This is the way he can give us the best performance and best way to do our way, playing maybe better sometimes. I think this is one process.
"For us it's very important to be competitive each match. We are being competitive at the moment. Being competitive we can then achieve a better way for how we can play.
"If we are competitive we can use different players in different moments, some with more skill, some with more capacity to do pressing and transition. We can use them if we, like a team, can feel strong in our mentality and being competitive and consistent each match."
