Glasner, who took Frankfurt to a Europa League triumph last season, was sacked in May, but the club let him stay on until after Saturday's final.
"I don't think it will matter to me until the final whistle. I will enjoy the evening. The game is important tomorrow, not Oliver Glasner," Glasner said in Berlin on Friday, explaining "I've had enough to do, Leipzig have kept me busy."
Frankfurt's Europa League win took them to the Champions League for the first time in their history this season. Despite finishing seventh in the league this season, a win on Saturday would see them qualify for the Europa League once more.
Frankfurt are chasing their sixth German Cup title, which would draw them level with Werder Bremen as having the equal second most titles after Bayern Munich's 20.
Sitting next to the golden trophy at Friday's press conference, Glasner took a glance at it and told reporters "everyone wants to take it home - it sparkles the same for everyone".

Born on the outskirts of Frankfurt, Eintracht captain Sebastian Rode said he had positive memories of the final, which he won in 2016 with Bayern and in 2017 with Dortmund. Glasner's side face holders Leipzig, who last year beat Freiburg on penalties to lift their first ever major silverware.
Leipzig manager Marco Rose, who was installed mid season and did not coach the Red Bulls to the title in 2022, said: "We're here to win the thing - we want to go that final step."
Rose said his side would not be overawed despite facing a crowd which is likely to be heavily pro-Frankfurt in the German capital. Frankfurt fans are known for travelling, having bought an estimated 25,000 tickets for a game at Barcelona's Camp Nou.
"We know Frankfurt fans are an inventive bunch and find their way to get tickets, but we've experienced things like that before. We'll also have a couple of Leipzig fans in the stadium," said Rose.
