Chelsea spent more than any other Premier League club in the summer transfer window and Todd Boehly looks set to splash the cash once again in January.
Following Graham Potter's arrival as manager of the Blues, succeeding Thomas Tuchel back in September, he has been unable to add players that fit his style of play. His first chance to do so will be in the new year when the January transfer window roles around with Chelsea being linked with a number of stars across Europe.
Cristiano Ronaldo is now without a club after mutually agreeing to terminate his contract at Manchester United having been linked with a move to Stamford Bridge over the summer. AC Milan talent Rafael Leao is on the Blues' radar but a deal in January could prove difficult to secure with the Serie A champions keen to tie him down to a new deal.
