Maurizio Sarri has admitted that Chelsea will need at least one year to prepare and reach Liverpool level.
The Blues have struggled in front of the goal on Sunday afternoon as they went a goalless draw with West Ham United.
The West London side will face Liverpool on Wednesday 26 in their Carabao Cup tie before they lock horns three days later in their Premier League clash.
Sarri, who admitted he could make as many as 11 changes for the League Cup showdown, believes Chelsea will once reach the Liverpool level.
“We have to face a team very very good, a team that has worked with the same coach for four or five years, I don’t know exactly,” said Sarri.
“They are a step forward than us at the moment. We have started to work altogether 40 days ago and less time with the international teams. For us, it is a bit early. We have to work and improve and then maybe in a year it will be the same level as Liverpool.”
“They have had one more day of rest. I want to see the picture of the situation tomorrow morning in the training session. I don’t know, maybe I will change 11, maybe five.”
