The agent of Wallace says they expect to start the season with Chelsea.
The former Fluminense fullback is flying to London today to launch his Chelsea career.
Federico Moraes told Calciomercato.it: "At the present state of things, Wallace will start with his companions in Malaysia for preseason with the Blues.
"We also expect to learn about Jose Mourinho's thinking on the player. He will travel overseas with Chelsea and then we'll learn their plans for him."
Moraes also said it was premature to talk about a loan move to AS Roma.
