Chelsea are preparing an opening bid for West Ham United midfielder Declan Rice. According to reports from Eurosport (via Metro), Chelsea are keen to bring their academy product back to West London. The Blues have been interested in Declan Rice for a long time. They first registered their interest in the midfielder last summer. In 2020, under the reign of Frank Lampard, Chelsea went on a major signing spree and many thought Rice would be a part of that transfer mania.The Blues were coming off two consecutive transfer windows where they had not signed a single new player (one due to a ban imposed by UEFA). Chelsea went on to invest over £200 million and signed several key players to restructure their team.Why Chelsea failed to sign RiceFrank Lampard wanted the Blues to prioritize signing Rice but a transfer failed to go through. West Ham were stubborn in their stance of letting Rice leave for a hefty fee (around £75 million). Moreover, Chelsea's management felt the need to invest in the attacking third was more urgent than buying Rice.Chelsea signed Timo Werner and Kai Havertz to revamp their attacking thirdChelsea are keen to bid for Rice this summerLampard has now been replaced in the hotseat by Thomas Tuchel but Chelsea's interest in Rice lingers on.
