Borussia Dortmund signing Sebastien Haller has thanked fans for their support after his shock cancer diagnosis.

Haller has been diagnosed with testicular cancer after feeling unwell at training last week.

The former Ajax and West Ham striker has taken to social media to thank the thousands of messages of support he's received since the news broke.

"Thank you all for the many messages of support and affection received from yesterday's announcement. My family and I thank you," he stated.

"Now I will focus on my recovery to come back stronger."
