Early career 1860 Munich Stanišić already played in the youth teams for the then second division
TSV 1860 Munich and stayed there until the summer of 2015.
SC Fürstenfeldbruck As a 15-year-old, the change took place in front of the gates of the state capital in the U16s of the then sixth division
SC Fürstenfeldbruck. With the club's younger B-Juniors, he was one of the top performers from the start and, as the second-best goalscorer in his team, contributed to the fact that the Bruckers were one of the two top teams in the B-Junior District League alongside 1. FC Garmisch-Partenkirchen. Already in May 2016, just turned 16, he was pulled up to the U17, in which he was also one of the top performers and with two goals in the remaining eight games of the season contributed to the U17 of
SC Fürstenfeldbruck being promoted from the regional league to the state league, in the junior B division, the third highest division behind the Bundesliga and Bayernliga. The Croatian also had a regular place in the team in the regional league, which just missed the Bayern league at the end of the season.
Youth career at Bayern Munich Stanisic was no longer there at this point, however, as
FC Bayern Munich had noticed him in the meantime and signed him for their U17s in January 2017. Hardly in Munich, Stanišić suffered an ankle fracture in preparation for the second half of the season and was out for the rest of the season. So he missed winning the German B-Junior Championship. In the summer of 2018, Stanišić played part of the season preparation with the professional team of
Bayern Munich and was also used in two games in
Klagenfurt and
Philadelphia. However, Stanišić continued to play everyday life with the A-Juniors and was the new team captain there in his second season. In January he had to undergo a groin operation and was absent for several weeks. In that season, too, the team missed the final round of the German championship, with fourth place even quite clearly, and the two cup competitions again ended early. He made his professional debut for
Bayern Munich II in the
3. Liga on 26 July 2019, coming on as a substitute at half-time for
Angelo Mayer in the home match against
KFC Uerdingen, which finished as a 2–1 win.
Bayern Munich Stanišić made his
Bundesliga debut for
Bayern Munich in a 1–1 draw with
Union Berlin on 10 April 2021, being named in the starting lineup as a
left back. On 1 July 2021, Stanišić signed a professional contract with Bayern until 2023. After impressing Bayern coach
Julian Nagelsmann during the
pre-season, Stanišić remained with the senior team, despite the original plan to be sent on loan to
Heidenheim. He was named in the starting lineup as a
right back on 13 August 2021, the first day of
Bundesliga, as Bayern drew 1–1 with
Borussia Mönchengladbach. On 15 October 2021, Stanišić extended his contract with Bayern until 2025. On 14 May 2022, Stanišić scored his first goal for Bayern in a 2–2 draw with
Wolfsburg. Later that year, on 12 November, he extended his contract with Bayern until 2026.
Loan to Bayer Leverkusen On 20 August 2023, Stanišić joined fellow Bundesliga club
Bayer Leverkusen on a one-year loan deal. On 10 February 2024, he scored his first goal for Leverkusen by scoring the first goal in a 3–0 victory over his parent club Bayern Munich. On 14 April, Bayer Leverkusen secured their first-ever Bundesliga title, in which he became the second player to win the competition with two different clubs in two consecutive seasons, following
August Starek in 1968 and 1969. A week later, on 21 April, he scored a header in the 97th minute of stoppage time in a 1–1 away draw against Borussia Dortmund, to extend Leverkusen's unbeaten streak in all competitions. On 9 May, he scored another 97th-minute goal in a 2–2 draw against
Roma in the
Europa League semi-final second leg, qualifying his club to the
final by winning 4–2 on aggregate, as well as prolonging his club's unbeaten streak to 49 matches, breaking the previous record set by
Benfica between 1963 and 1965.
Return to Bayern Munich On 27 June 2024, Stanišić extended his contract with Bayern until 2029. On 10 March 2026, he scored his first Champions League goal in a 6–1 away win over
Atalanta in the first leg of the
round of 16. == International career ==
