Thomas Muller revealed Bayern Munich's players were exhausted before the end of their DFB-Pokal final against Borussia Dortmund that Pep Guardiola's men went on to win 4-3 on penalties.
Following a 0-0 draw over 120 minutes, Manuel Neuer's save from Sven Bender proved key, with Muller and Douglas Costa converting from the spot to end Guardiola's three-year reign on a high.
Bayern have now won a record 18 Pokal titles and completed the league and cup double again, with Muller hailing the mental strength of his team-mates as a vital factor in their victory.
"Penalties are always a mental thing. We were spent after 120 minutes," Muller told ARD.
"We'd have been gutted if we've not on the game. We really had chances to score. I think we played well but the final touch wasn't there for us.
"We know how strong Dortmund are - Marco Reus and [Henrikh] Mkhitaryan were really dangerous - but we're just delighted to have won an intense game.
"It could have gone either way, that's what happens in the cup."
