Playing alongside his fellow Iranian international Mehdi Mahdavikia, he had just 12 appearances, so he left the club for VfL Bochum to show his real ability.

During his last season there he scored 16 goals, helping Bochum to finish fifth in the Bundesliga and qualify for the 2004–05 UEFA Cup.

This prompted Bayern Munich to grant him in a €2 million contract, hence giving him the chance to follow in the footsteps of Ali Daei.

Hashemian was later invited for the second round of World Cup Qualifying playing in Iran's 1–1 tie versus Saudi Arabia.

[9] Accepting a job offer by Thomas Bliemeister, then-coach of SV Halstenbek-Rellingen who took position as the club's technical director, he was appointed as the coach on 26 October 2012.

[7] In July 2013 he signed with Niendorfer TSV, but left the team in the mid-season in order to pursue his professional training.
