Holger Rune sealed the BMW Open Munich title earlier on Sunday after seeing off Botic van de Zandschulp prevailing in a thrilling 6-4, 1-6, 7-6 win.
But Rune admitted post match to battling through physical issues saying he was not fine but found a way through saying he felt 'awful' in victory.
"To the end. I tried everything I could to to come back into the match, and it was, I think for a, a perfect final, you know, we both pushed each other to the limit," said Rune.
"I'm not fine. I feel awful. And I said, it is what it is when you're in this situation, you know, it's the last match, it's the last push. So, I tried to find a way that could help me a little bit to not be as hurt. But again, it was a struggle and, you know, I managed to get it done."
