They are still under the illusion of past glory and it would take them more than two seasons to come back to the Chelsea that everyone knows
Their performance this season means that gamblers should not expect much from Chelsea. I agree with what you said that it will take at least two seasons for Chelsea to rebuild the team into the Chelsea that everyone knows. Maybe even longer than that. I just hope that Chelsea will not become like United where they have been a mid-table team for so long.
