Marcos Alonso has completed his move to Chelsea, and further action could follow across Europe with Leicester closing in on Islam Slimani.
Chelsea have completed the signing of Marcos Alonso from Fiorentina, while Manchester City sent a further three players out on loan.
Reports linking Alonso to Chelsea had grown in the past week, but after initially denying a deal was close on Monday, Fiorentina announced the transfer on Wednesday.
The former Bolton Wanderers and Sunderland left-back's switch was quickly followed by confirmation from Chelsea, who revealed a five-year contract has been signed.
Alonso's arrival at Stamford Bridge may not be Chelsea's final move of the day, with a sensational return for Paris Saint-Germain defender David Luiz confirmed to be on the brink of completion.
