Pioneers when it comes to big spending, Chelsea will need a bulldozer to knock down Sampdoria's €100m (£83.5m) valuation of the Italy international.
Il Corriere dello Sport reports the Blucerchiati have already rejected a substantial offer from Juventus. Two weeks ago Samp president Riccardo Garrone said he wouldn't even sell his player for €100m.
That was viewed as an unrealistic valuation, and a clear attempt at scaremongering the interested clubs.
However, Ancelotti is confident £18 million will be the tip of the iceberg for Sampdoria and enough to defrost talks and reignite a deal.
