On October 22, 2008, Sundblad was named head coach of Herner EV,[1] a minor league team in Germany.

On December 3, 2009, he accepted a position as assistant coach with the Kölner Haie[2] organization of the German elite league DEL.

He served as head coach on an interim basis, when the club sacked Bill Stewart in November 2010,[3] before returning to his role as assistant.

Sundblad left Köln after the 2012–13 season, taking up an offer from fellow DEL team ERC Ingolstadt where he became head coach.

[4] After finishing the 2013-14 regular season in 9th place, Sundblad directed his team to one of the most surprising playoff runs in DEL history, making it to the finals where they defeated Köln to give ERC its first ever German championship.
