Chelsea chief Frank Arnesen says it's no time to celebrate after see several youngsters make their first team debuts this season.
But Arnesen told chelseafc.com: "It is a long process and we will not be in heaven just because the young players are playing now in the first team, and also there were not doubts one year ago when they didn't play,' he begins to explain.
"There is always a natural development for young players and one thing that has been very important is that they have been training every day at the highest level - training with players like Ballack, Terry, Lampard, Drogba - and I know from my own experience when I was 18 coming into the team at Ajax that you learn so much every day in this period of a young player's life.
"This is very much the priority and then the games come later. Every minute Kakuta, Borini, Bruma and Sturridge get in the first team is a bonus, and it is good to see Nemanja Matic as well who is another young player.
"With all respect, he is from a small club in a small country that didn't have resources to do what we are doing here with him and he is developing very quickly, and all those players are doing well."
