Chelsea will face competition from Serie A side Napoli to secure the services of Porto full-back Alvaro Pereira.
Pereira, 26, was expected to follow former Chelsea boss Andre Villas-Boas from Porto to Stamford Bridge last summer, but that move failed to materialise.
And despite penning a new long-term deal with the Portuguese club at the close of the last transfer window, Pereira has already indicated his willingness to entertain any offers that come his way this summer.
With the departure of Jose Bosingwa, Chelsea boss Roberto Di Matteo is expected to be on the hunt for a new right-back, and Pereira is still believed to be on the club's shortlist, despite the exit of Villa-Boas.
However, Italian publication Tuttosport claim Napoli have already sounded out the player's agent over a £12.8 move for the full-back.
