Jurgen Klopp and Pep Guardiola have both passed comment on Chelsea's transfer spending after breaking records last month. The Blues signed eight new players and also made Enzo Fernandez the most expensive player in the league's history, taking their total spending under Todd Boehly over £550million.
The way that the business has been conducted has attracted plenty of attention and criticism, especially considering the lack of spending power across the rest of Europe. Such was the total outlay, Chelsa's window was more than the other four of Europe's top five leagues combined.
Given that January is often a month said to be tough for buying new players these actions from Chelsea smashed those myths. It has been impossible to ignore and has led to some of their rivals being questioned on what it means for the future.
