After back-to-back wins to start his reign as Hannover coach, thoughts of qualifying for Europe again next season had started doing the rounds.
A 2-0 loss to Schalke last weekend - Korkut's first defeat in charge - has brought more realism back to the club, according to the Turkish coach, who continues to stick to his original objectives.
"Our main goal is a relaxed season," he said at a press conference. "A season without any worries."
That goal would be facilitated by only a second away win of the season at the Coface Arena, although Korkut has warned it will not be easy against a side who can move level on points with sixth-placed Wolfsburg with a win.
"They're on a good run and won't leave us in any peace and quiet," he said. "We're going to have to give it all we've got."
Hannover may still have the worst record away from home in the Bundesliga this season, but that is not going to obscure Mainz coach Thomas Tuchel's view.
"The situation has turned completely with the second half of the season," he said. "It's going to be an extremely difficult game."
The 4-1 defeat at the Niedersachsenstadion is no longer of importance either.
"We're certainly going to try to do better than we did back then," said Tuchel, who has a doubt over South Korean international Park Joo-ho, who was unable to train fully this week.
