Sebastien Haller returned to training with former club Ajax on Tuesday as part of his recovery from a testicular tumour.
Haller received the diagnosis shortly after signing for Borussia Dortmund for £31m in July following an impressive 2021-22 season which saw him score 34 goals in all competitions for the Dutch side.
After feeling unwell during Dortmund's pre-season tour of Switzerland, he underwent tests which revealed a malignant tumour.


He has since undergone chemotherapy and his return to the training pitch is a welcome step in the striker's recovery.
