[2] On 28 December 2019, Pelzer was announced as the new technical director for Major League Soccer franchise Chicago Fire.

He made his debut as a reserve player before making his first team appearance in the Football League Cup against Walsall.

He returned to Germany after eighteen months at Ewood Park, joining his hometown club, SV Eintracht Trier 05 who were fighting relegation at the time.

Linked to A.C. Perugia Calcio, Real Murcia, Hannover 96 and Borussia Mönchengladbach he instead was advised by his agent to make the short journey to 1.

Despite ambitious plans for promotion with the signing of players such as Mustapha Hadji Saarbrücken suffered relegation, and Pelzer left the club.

Pelzer left the club in the summer of 2007, with the intention of returning to England following trials with Hull City and Plymouth Argyle.

On 12 January 2009, he moved up a league to join Bundesliga 2 side Rot-Weiss Ahlen who had tried to sign the player during the previous summer.

The club made major changes to the promotion winning side, with Pelzer making just 14 league appearances for season.
