He told chelseafc.com, "In the squad we have Thiago Silva and Raheem Sterling who have experience, or Marcus Bettinelli who maybe is not playing but I want to say that he is doing a fantastic job because he's helping the young guys. So we have experienced guys also in the squad.
"That is not going against the project. That is trying to have some guys who are helping the young guys to be a professional, to perform, to understand what the Premier League means and the standards of Chelsea."
Pochettino also said: "We are in a project where 80 or 90 per cent of the players are young and maybe they need to grow together. Of course they need some help. That is why we are here, to help them in this process, to become leaders and be improving.
"But we are talking about so many players who only arrived at Chelsea and the Premier League this season. John Terry was young also and needed to build, he wasn't already the leader of the team at 18 or 19.
"It's like if you compare Nicolas Jackson with Didier Drogba in his first season. Jackson could be a leader, but Drogba wasn't the leader in his first season. So of course with time we can create good leaders."
