#3 Inefficient transfers
Few transfers Chelsea made this season doesn't make much sense. They have made some mistakes when they entered into the transfer market after the title-winning campaign last season. And these lapses have happened from their manager and the board.
One of the most important players who helped them to become the champions last term was Diego Costa. If Conte handled the situation more professionally, Chelsea wouldn't have lost their most lethal weapon. If losing Costa was a mistake from Conte, losing Nemanja Matic to Manchester United should be pinned on the board.
Chelsea, who added Tiemoue Bakayoko to their ranks, then sold Matic to title rivals United for £40 million and brought in Danny Drinkwater for £35 million, which simply doesn't make any sense. Chelsea are now not able to control the games in the midfield as Bakayoko is not able find the form he had at Monaco last term.
Meanwhile, Matic's arrival has given freedom for Pogba at United. Also, they sold Nathan Ake to Bournemouth and Loaned out Kurt Zouma to Stoke City. Both youngsters are on fire this term for their respective clubs as Chelsea finding it hard to shore up their defence.
