There is nothing to learn from it. When KDB left, we won the PL. It took him four years or so to grow and come back to win one. The team is more important than any talent because there will always be new talent. If Estevao won't be patient (I'm not saying he isn't), he can force a move away like KDB, Mata, Salah, Lukaku, and recently Veiga and co. Chelsea will move on. They can become the greatest elsewhere. It doesn't matter. It's either you are with us or you go. Chelsea doesn't have to change plans over one talent as if he is the only one we have.
