The Blues won the Champions League last season and are now considered one of the top contenders for the Premier League title.
And Jorginho says Tuchel is two different characters when it comes to management.
Speaking after Tuesday's win over Zenit St Petersburg in the Champions League, Jorginho said of Tuchel: "He works hard, he wants the best from us, so he tries to give his best as well to help everyone because he knows what we can give and that's what he demands.
"But I think it's two different guys because the guy you see on the touchline is not the same guy outside the pitch.
"He is very friendly outside the pitch and on the pitch he is just focussed and wants to win the games and wants the best from us."
