Eintracht Frankfurt has secured its place in the Bundesliga for another season after securing a 2-1 victory over VfL Bochum on Saturday.
The win means that Eintracht will be back in the top flight next season, with manager Frank Rijkaard delighted to have his side secure their spot in Germany's premier division.
"We deserve this," Rijkaard told reporters after the match. "We worked hard all season and we're very happy."
Eintracht's victory came thanks to goals from Kamada and Kostić, who both assisted each other in the final stages of the game.
Kamada scored the opener for Eintracht in the 47th minute, before Kostić equalized just three minutes later.
However, Eintracht were able to hold on for the win, with Kamada again coming up trumps in the final stages of the game.
"The result is important because it secures our place in the Bundesliga for another season," said Kamada. "I'm really happy about this."
For Kostić, the goal was a dream come true.
"I've always wanted to play in the Bundesliga and now I've done it," he said. "It's a great feeling."
Eintracht's success comes at the expense of VfL Bochum, who were relegated from the Bundesliga after finishing bottom of the table.
Despite the defeat, manager Christian Gross was proud of his team's efforts throughout the season.
"It was a tough fight and we gave everything we had," he said. "But we can't be too disappointed because we did our best and we'll try to improve next year."
