Tuchel says the game against the Rojiblancos at Stamford Bridge will be similar to that of the first leg.
The game in Bucharest was very tactical which had fine margins as Olivier Giroud’s second half goal gave Chelsea an advantage heading into the second leg.
Speaking to the media before the game, Tuchel was asked about what to expect against Diego Simeone’s men.
“For me I expect more or less the same like in Bucharest, they have Trippier, Jimenez and Carrasco back, that changes a little the structure and style of attacking,” the German coach said.
“It gives them the freedom to attack with Carrasco and Trippier on the side. Llorente is available on the half positions, so that changes their approach a little.
“But in general I expect more or less the same. A team which is hard to play against, hard to find spaces behind the lines, and behind the last lines, and for sure super hard to create chances.
“It's a big challenge for us like in the first leg, but we played an amazing match there and we want to repeat the same performance to be able to go through.
“We know how hard it is to beat Atletico but this is our plan.
The former Paris Saint-Germain coach was further asked if he was surprised by the defensive setup of the Spanish side in the first leg.
Tuchel added: “Well I believe that every club has its DNA and characteristics, it's Diego Simeone, and Atletico became one of the toughest teams to beat in Europe.
“So this is their characteristic, they rely on a disciplined, hard-working, super organised defence. At the same time they have incredible quality to attack and to play also possession game.
“For me it's a very complete squad and you have to be aware of everything. They are able to press high, defend low, play for possession. But in most of the games they rely on a hard-working defence, so this is the characteristic of the club, the characteristic of the coach.
“I don't think the result from 1-0 changes too much in the approach at the beginning of the game. Both teams have to adapt to the questions that are asked, and we know it can change within seconds.”
