The reason why Chelsea sacked Tuchel

Chelsea sacked Thomas Tuchel and replaced him with Graham Potter. Reasons as to why are coming out months later and, according to 'The Times', the change in the policy of signings could have been the reason.
The club's revolution came with the arrival of new owner Todd Boehly. When the Stamford Bridge board looked for a new midfielder in the transfer window, the German manager did not give his full approval of said move.
That man in the midfield has ended up being Enzo Fernandez. The flamboyant World Cup champion with Argentina landed in London for the eye-watering sum of €121 million, and will stay there until 2031.
Football does not have a long-lasting memory and, despite Tuchel's hat-trick at Chelsea - Champions League, European Super Cup and Club World Cup - his time there did not have a happy ending and he was sacked.
