"I signed for Dortmund and everything was fine," he explained. "I think my family and everyone was quite happy with the situation,” Haller told ESPNNL.
“And then I don’t know. I felt something uncomfortable in my belly. And then from there it went really, really quick.”
He added: "The next day at 9 o’clock in the morning I had an MRI scan. They said, ‘oh, we see something. We should check again’. So I went to have a biopsy because they thought it was maybe a tumour.
“I had lots of examinations in less than 24 hours. I had to wait for surgery to make sure and to know exactly what it was. They knew directly that it was this [diagnosis]. So I was really lucky to have all those checks so quick. And now I know."
