On 15 January 2022, Wienroither joined
Arsenal from German club
1899 Hoffenheim for an undisclosed fee. In May 2023, Wienroither suffered a ruptured ACL, 18 minutes in from being subbed on in during the 2nd leg of the semi final of the
2022-23 UEFA Champions League game against
VfL Wolfsburg. This was the club's fourth ACL injury that season after
Beth Mead against
Manchester United in November 2022,
Vivianne Miedema in December 2022 against
Lyon during the Matchday 5 of
2022–23 Champions League group stage and
Leah Williamson in April 2023 against
Manchester United. She made her return from injury 328 days later against
Bristol City as an 80th minute substitute for
Emily Fox. On 30 January 2025, it was announced that Wienroither would join
Manchester City on loan for the remainder of the season. On 15 August 2025, it was announced that Wienroither would be making the move permanent, leaving Arsenal just a year after renewing her contract at the North London club. She signed for Manchester City until 2027. ==International career==
