Chelsea are reportedly plotting a £156m double transfer swoop with one of the players they are interested in recruiting playing in the Championship last season.
The Blues are expected to splash the cash again when the January transfer window opens having already spent over £1billion on new players since Todd Boehly's ownership takeover.
Mauricio Pochettino wants to make improvements to his squad following an unconvincing first half of the season that has left Chelsea in midtable and aiming for silverware in the Carabao Cup.
Chelsea's biggest struggles has come in the goals department and Pochettino is expected to bring in a new striker, with a Sporting Lisbon star being discussed for a transfer.
