Very tragic, the money spent by Todd Boehly could not be used by Potter to improve Chelsea performance. The Chelsea squad is already filled with quality players, but there are no signs of improving performance yet. The decisive action taken was very appropriate, Potter really deserved to be sacked because he had not been able to provide anything of value since being appointed as head coach of Chelsea. Potter's replacement will receive a baton full of thorns, whoever replaces Potter must be able to make Chelsea able to compete with other elite teams again.
Chelsea's worsening condition will be difficult to face Real Madrid. This situation is very profitable for Real Madrid, apart from acting as the home team in the first leg, Madrid is currently also in its best form.
Less experienced with manage star player I think problem faced by Graham Potter since become Chelsea manager and he was spent much money for signing star player but not effective until Chelsea's position dropped to 11th standings. I don't know about Graham Potter capacities how come Chelsea's management keep believing with him until several bad performance. I don't sure with new manager replacing for Graham Potter position have capacities for returning back Chelsea to the top fourth position.
Until two days Potter's sacked not any new update who will replace his position because Chelsea have to play in Champion League quarter final against Real Madrid, seems have two weeks later before this games and Chelsea have hurry up reach personal agreement or deal with new manager.
