Jannik Wanner is a German left winger, born on 20 December 1999 (age 26), now with St. Polten. He is an established professional rather than a name with any obvious Celtic connection, and his career is best read through steady second-tier output rather than noise.
His most productive league season came with SKU Amstetten in 2024-2025, when he scored nine goals in 30 appearances. For a wide player, that is a useful return, and it appears to have been the spell that put the clearest shape on his senior career to date.
Wanner is currently valued at around £170,000, according to Transfermarkt. At St. Polten, he remains a left-sided attacking option with a career built on practical contribution rather than profile.
