The Blues beat their bitter London rivals 3-0 on aggregate across the two-legged League Cup semi-final, but boss Tuchel has rejected any ideas of a mental advantage.
“We have played three matches in such a short time which is pretty unusual and uncommon normally, that is why they know what we do and we know more or less what they do," said Tuchel.
“But it is another game for us to show up. They will come into this game from a late victory over Leicester which gave them a boost and we came from two wins in the Carabao Cup that should give us some confidence.
“But it is not about having whatever advantages and if we are philosophical about it: we have to deliver and have the right attitude to deliver a top performance."
