'Work, eat, sleep, repeat': Tuchel on first week as Bayern boss

"My week was 'work, eat, sleep, repeat'," said the manager, who was appointed after the surprise sacking of Julian Nagelsmann.

"We need to make it work, no matter how much time there is."

Bayern host Dortmund with the visitors one point clear at the top of the Bundesliga table, ahead of a German Cup meeting with Freiburg and a Champions League quarter-final clash with Manchester City.

"April and May are very important for clubs like Bayern, who define themselvethroughs  titles."

It will be a reunion of sorts for Tuchel who spent two years in charge at Dortmund, taking over when Jurgen Klopp left in 2015.

Tuchel, however, said he would not use his sacking by Dortmund in 2017 as motivation for this weekend.

"It's been six years" Tuchel said. "When I played in Dortmund with Paris, I was hugged by a lot of people.

"A lot of people, including me, regretted that my time came to an end (at Dortmund) but it's way too long ago to hold grudges."

Tuchel admitted he had little time to determine a starting XI, saying "it's going to be a very unfair line-up tomorrow because I have to rely on my first impressions."

The manager said he "tried not to overload the players after a turbulent week", saying "less is more".

Tuchel told the press conference his firing from Chelsea "still hurts", saying he missed the "extraordinary bonds" he had with many at the club.

"I was no longer a part of this group, where it felt like a family. But now I have a new challenge."

Dortmund come into the match having won nine of their 10 league matches in 2023, with Bayern winning just five in the same period.

"It's a big match, a huge challenge for us to step up against a team on a run like that, but it brings out the best in us."

Tuchel said forward Jamal Musiala was in line to return from a thigh injury which saw him miss Germany's friendlies, but a decision would be made on Saturday morning.
