Sterling has already had a physical and is about to sign a £47.5 million, with the option of a further £50 million, deal with the Blues.
The England international might make his Chelsea debut against Arsenal in the Florida Cup final the following Saturday or in Charlotte on Thursday.
Thomas Tuchel, the manager of the Blues, made it obvious that he wants Sterling to play a significant part in his revamped offensive scheme.
Sterling will sign a five-year deal that will be much more expensive than his current weekly salary of £300,000.
He can choose to make it last for an additional year.
