The Blues have come up openly to offer £70m in order to bid for the signature of Declan Rice.
It must be noted that the former Blues graduate is been monitored by Frank Lampard to enable him play him in the middle of a back three next season.
Similar report shows that the Blues are ready to offer a £45m for the England international which is not sure if the Hammer will willing accept the offer.
Club record shows that Rice still have four years remaining in his contract with the Hammers and it is believed that a bid of £70m will place the transfer in a better position for the Blues.
Other club in competition for the British player is United but they are more concerned about getting Jack Grealish.
