Biereth spent the season on loan with two clubs, first playing for Motherwell in the Scottish Premiership before moving to Sturm Graz in Austria for the second half of the season.
That proved an inspired switch, with the striker going on to win his first two trophies in senior football.
First, Biereth helped his team to lift the OFB Cup, scoring one and assisting one in his three appearances from the quarter-finals onwards. After that, he helped his team to secure the Austrian Bundesliga title with five league goals and three assists.
Biereth ended the season with 15 goals and nine assists between his two loan spells, a goal contribution every 111 minutes.
