Despite being heavily linked with the France international and an array of different left wing-backs, the Blues did not make a first-team addition during the opening month of 2022.
However, Tuchel has insisted that he pleased with how the month progressed, hinting that there was little desire to get a deal for Dembele over the line at the midway point of the campaign.
Speaking to reporters at a press conference, Tuchel said: "I'm very satisfied because it was a calm window. To be calm is always the best thing.
"We were open to things. I did not have contact with Ousmane. There was no contact in winter, no contact between us."
Chelsea have been tipped to make a move for Dembele in the summer with the player due to depart Barcelona on a free transfer.
