But he travelled to Belfast with the rest of Chelsea’s Champions League-winning squad and could be involved at Windsor Park on Wednesday night.
Tuchel has the chance to immediately win a second piece of silverware after last season’s Champions League triumph – but says he has no concerns about the challenge of maintaining the levels set in his first few months in charge.
He said: “It doesn’t feel like pressure because this is what we demand of ourselves, me at the very first point. I demand to get better every day, use my experience and to be the best coach I can be every single day.
“The courage now is to face the challenge, does anybody have a recipe how to do better after a Champions League victory? I don’t know, it was my first win so I think the courage is to face the challenges, step up and keep on demanding.
“We have some things we need to develop and improve, there were things that were very strong last season and we have to maintain that level.
“We have to, clearly, rebuild the same spirit that put us in the position to get these results. “There are a lot of different tasks to fulfil and the most important is that we don’t lose sight by thinking too much about pressure and expectations.
“It is an everyday process and if you take care with it, you don’t get too distracted and it doesn’t get complicated.”
Chelsea predicted XI (3-4-2-1): Mendy; James, Thiago, Rudiger; Pulisic, Kante, Kovacic, Chilwell; Ziyech, Werner; Havertz
