Chelsea manager Jose Mourinho is preparing a shock move for Tottenham midfielder Mousa Dembele.
The Sun of Sunday reports that the Belgium international, who would cost £12 million, could be signed as a replacement for John Obi Mikel, who is expected to leave Stamford Bridge before the new season kicks off.
Dembele's Belgium team-mate Axel Witsel is also being linked with the Blues and The Sun suggests the midfielder would cost in the region of £24 million.
Chelsea have also scouted Marseille's 22-year-old Gianelli Imbula, although Valencia are apparently the frontrunners for the French midfielder.
The agent of Manchester City striker Edin Dzeko has denied the Bosnia striker has contacted Chelsea about a move to Stamford Bridge and says the 29-year-old will most likely stay at the Etihad.
Agent Irfan Redzepagic has told ESPN: "Every day they are linking him to another team. First it was Atletico, then Juventus and now Roma, Chelsea... these are all journalists' guesses and speculations, repeating with every transfer window. I'm bored with repeating that there's nothing in it.
"Edin is currently on holidays. He hasn't rejected any offers, because there simply weren't any. That is the whole truth of it."
