If Chelsea are successful in signing Benfica midfielder Enzo Fernandez, it will take their total spending since Todd Boehly's takeover last summer past the £550m mark.
According to Transfermarkt, recruiting Fernandez for 120m euros (£105.6m) would take the club's January spending to 328.5m euros (£288m) on eight arrivals as they try to turn around the form that has left them 10th in the table.
It comes after a summer in which they spent a Premier League record £270m - the second-highest summer spend by any club in the world after Real Madrid (£292m) in 2019 - and contributes to a record £2.
