The club are working hard to secure new players so they can mount a proper title challenge under Frank Lampard next season.
And their next target appears to be Gerson from Brazil.
Fox Sports claims that the 23-year-old is wanted by the Stamford Bridge club.
The club do not want to lose Gerson, but would sell him if they could make such a profit in a short space of time.
The central midfielder would bolster Lampard's options in the middle of the park.
