On what it would mean to win the FA Cup, Tuchel said: "This would be huge, absolutely. The FA Cup is one of the most prestigious cups in the world, it is played at Wembley and even if you are a little boy in Germany with no Internet in those times, and no sports channels to watch every game like nowadays, you know the words FA Cup and Wembley.
"You know these words and you know that this is a big, big game to play in and a big goal to achieve. But you know me better now and the approach tomorrow is that this game is the most important game of this cup campaign.
"It is a decisive match and an elimination match. We all know very well that we can expect everything in a game of football. We have to go step-by-step but for sure we do everything to prepare to win this game and get to the next round."
