[8] After his spells in the Swiss Super League with FC Basel and then FC Zürich, where he built a successful strike partnership with South Africa striker Shaun Bartlett,[9] Frick began catching the eyes of scouts from some of the best leagues in the world, including the Serie A in neighboring Italy.

[1][11][10] Frick's good form helped Arezzo reach the Serie B promotion play-offs but they lost to Livorno 5–1 on aggregate in the semi-finals.

He would play alongside other promising youth including Alberto Gilardino, Adrian Mutu, Mauro Camoranesi, Sebastien Frey, Martin Laursen, Massimo Oddo, and Marco Cassetti, all of whom would both go on to have successful careers.

[18][19][11] Frick was described at the time as a player with "pace and predatory instincts [that] make him a danger inside the penalty area and he has proved he can score against tough opponents.

[1] Frick decided to end his professional career and go part-time, returning to his first club FC Balzers in July 2011.

[23] He went on to score his first goal for the national team in a 1998 FIFA World Cup qualification match against Romania in September 1997.

[25] Frick had a falling out with both the national coach, Ralf Loose, and the Liechtenstein Football Association near the end of the 2002 World Cup qualification stages, and he was left out of the team.

This episode is chronicled in Charlie Connelly's book, Stamping Grounds: Liechtenstein's Quest for the World Cup.

[26] After changes concerning both the Liechtenstein Football Association and the coach, Frick returned to be part of the squad, which included playing in both games against England.

[24] Frick announced his retirement from international football in October 2015, at the age of 41, after 125 appearances and 16 goals for the Liechtenstein national side.

[23] He made his final international appearance for Liechtenstein in a 3–0 defeat to Austria in a European qualifying match on 12 October 2015.
