Benfica midfielder Nemanja Matic continues to be linked with a return to Chelsea.
The London Evening Standard says speculation is rife as to the identity of two potential signings, with Benfica midfielder Matic a name repeatedly mentioned in informed circles.
It is also thought that Jose Mourinho is weighing up a move to raid his former club Real Madrid for left-back Fabio Coentrao, who is understood to be available at the right price. Real paid £25m for the 25-year-old in July 2011 but are willing to accept a fee in the region of £18m.
Centre-back Pepe is also available and despite recent disagreements with Mourinho is another possible target at a reduced price.
