'I was focused like it was a big game': Sebastien Haller reveals how he used a sporting mentality during his battle with a testicular tumour... as the Borussia Dortmund striker insists he 'enjoys every moment a bit more' after his incredible return

Sebastien Haller has opened up on his attempts to return from a testicular tumour and revealed he treated chemotherapy 'like a big match'.

The Borussia Dortmund striker joined the club from Ajax for £31m in July, but fell unwell in training just two weeks later and medical examinations confirmed that he had a tumour.

Haller had to undergo chemotherapy and two operations in the final months of 2022, but returned to action last month.

He has since played six times in all competitions for Dortmund and is continuing to build up his fitness.
