2) Eliaquim Mangala (FC Porto)
The France international has been heavily linked with the west London club of late, although the Blues are believed to not be the only big-name club currently interested in the centre back.
However, with the 23-year-old now thought likely to leave the Estadio Dragao when the summer transfer window does finally reopen for business, then do not be surprised at all if the player ends up at Stamford Bridge next season.
