However, after a lean spell in the mid-1990s, during which FK Austria were over-shadowed by SV Salzburg, Flögel decided to try playing abroad, eventually signing for Scottish side Heart of Midlothian in 1997, after a trial with Dundee United.

Flögel enjoyed instant success with the Edinburgh club, helping them end a 36-year trophy drought by winning the Scottish Cup in 1998.

Although initially considered a midfielder, Flögel displayed great versatility during his time with Hearts, and played in every outfield position during a five season-spell at Tynecastle.

In 2002, Flögel returned to former club FK Austria, who were buoyed by significant investment from billionaire Frank Stronach, and won the Double in his first season back in Vienna.

After being left in the international wilderness for five years (from 1995–2000), his consistent form with Hearts earned him a recall to the Austria national side and he increased his cap tally to 37, in which time he scored three goals.
