Dortmund, Germany: Borussia Dortmund striker Sebastien Haller made his first competitive appearance since recovering from testicular cancer on Sunday, coming on in the second half against Augsburg and describing his welcome by more than 80,000 fans as "unforgettable".

Haller came off the bench to rapturous applause, bringing the 82,000-strong crowd at Dortmund's Signal Iduna Park to their feet.

"The welcome I received was something unbelievable, unforgettable," Haller told German broadcaster DAZN.

"I was just happy to be here and to take my first steps on the pitch.

"It's something we can take with the team, this atmosphere, we can use (it) to win games."
