Asked about the biggest development over the course of the season, he stated: "There's so many things.
First of all, you need to realize you are at Chelsea and the demands of Chelsea is completely different to other clubs.
We have players with potential to be amazing players. Potential means we are talking in the future, not in the past or the present.
"Also, there are many foreign players needing to adapt from coming from outside. Then it's to deal with your reality change, when you arrive here for all of the reasons we already know and then to build a team a team that can behave like a team.
"It's not to put 10 people in this room and expect them to all be friends. With the time and patience, they start to link and to bond, to create this complicity that is so important to translate to the pitch."
On his own man management style, he added: "The quality, your personality, we are a coaching staff that are very supportive and try to understand. At the same time, we are tough people because we always try to help and to push them to achieve their best level.
"It's not always nice. But I think through our experience and quality as a coaching staff, we try to decide for every single player because every player is different and all suffer in a different way with injuries. Try to personalise the way to talk, the way to approach, to communicate and to help with different players."
