[1] Prior to the 2020–21 season, Strauß returned to Austria to join second division club Blau-Weiß Linz on a contract until June 2022.

[6] He would quickly establish himself in the starting lineup of the Vorarlberg-based side, first as a defensive midfielder under head coach Damir Canadi, and, as the season progressed, as a centre-back alongside Jan Zwischenbrugger.

[8][7] Strauß scored his first goal for the club on 2 April 2022, securing a 2–2 draw and a completed comeback against Admira Wacker Mödling deep into injury time.

He replaced Lukas Gugganig in the 60th minute, before being forced off due to an injury; it was later confirmed how he would be sidelined for several months as he had "torn his ankle ligament".

[13] He was set to return to action on 2 October for the league match against SV Ried,[14] and found himself in the starting lineup from then on under new head coach Miroslav Klose.

[16][1] After having been ruled out due to injury at the start of the new season, Strauß established himself as a starter early under new head coach Joachim Standfest.
