Chelsea are becoming fed-up with Roma's tactics over their pursuit of Radja Nainggolan.
The London Evening Standard says Chelsea put talks with Roma on hold after having two bids rejected, the last of which was worth £27.4 million.
The Serie A side will not sell for less than £37m and Chelsea are unwilling to pay that for a player who turned 28 last month.
As an alternative, Chelsea are interested in Leicester midfielder N'Golo Kante, who has a £20m release clause in his contract.
