Lollichon told chelseafc.com: "For Ross it is slightly different, he needs a lot of things. We are lucky because he is a very good man, and an intelligent man. He wants to understand why I suggest one exercise or another, which is important. If Ross is just like a machine it is not good.
"He needs to work on his technique, physically and tactically, and I am very happy with him now. Since July, Ross improved in each aspect. In three months it will be very interesting to see the outcome of our work. He has already improved, but he still needs to work."
