Chelsea U21 coach Mark Robinson is happy seeing his players train with the senior squad this past week.
Robinson says manager Mauricio Pochettino is enthusiastic about the academy.
He told chelseafc.com: "A lot of the lads went across to the first team to help with their numbers during the international break. For the ones that didn't, we've done extra individual work that is more specific to their development needs.
"Even for the lads that went across to the first team, we put on extra sessions in the afternoon so that they were still getting their individual development work. So we've honed in on their own action plans and individual development.
"I speak regularly with Jesus [Perez, assistant head coach to Pochettino], pretty much on a daily basis. I get feedback, positive or not positive, but it's usually always been positive.
"If they go across and do well, which they have done, you feel good. You take a lot of pride in how they approach things. The last thing you want to hear is their application isn't what it should be. Fortunately, that has always been good and, on top of that, you want them to show quality. The feedback has been good and that is always nice to receive."
