The four players -- Prabhsukhan Singh Gill, Suresh Singh Wangjam, Rahim Ali and Rahul K P -- all of whom are part of AIFF's developmental team Indian Arrows -- will be reporting to the Camp in Delhi from July 28 onwards, along with 30 others.
The final is slated for September 15.
Constantine stressed it's important to see whether the youngsters are up to the challenge or not.
"We are always looking down to the age groups to see if these players can make the step up the ladder. I have always put a great deal of importance on the youth and have stuck to the same philosophy -- this camp is no different. Quite a few youngsters have been provided with a chance to prove their worth," he added.
"Heading to a tournament with such a young team is going to be a challenge but that's what we want. We want to find out that particular player who can push the extra bit to achieve the desired result, who can take up the extra responsibility to force himself into the team."
