Schreiber played his youth football by
FC Basel and advanced to their first team for their
1993–94 season and signed his first professional contract under head-coach
Claude Andrey. After playing in three test games Schreiber played his domestic league debut for the club in the away game on 14 August 1993 as Basel won 3–0 against
SR Delémont. During that season his teammates were the likes of Swiss international goalkeeper
Stefan Huber, defenders
Massimo Ceccaroni,
Marco Walker and
Samir Tabakovic, the midfielders
Mario Cantaluppi,
Martin Jeitziner,
Admir Smajić and
Ørjan Berg and the Swiss international strikers
Dario Zuffi and
Philippe Hertig. Together they won the promotion/relegation group and became
Nationalliga B champions and thus won promotion to the top flight of Swiss football. This after six seasons in the second tier. Following the promotion season he stayed with the club for another two seasons before he moved on. During his time with the club, Schreiber played a total of 14 games for Basel without scoring a goal. Four of these games were in the
Nationalliga B and
Nationalliga A, one was in the
UEFA Intertoto Cup and nine were friendly games. Following his time with Basel, Schreiber moved on and played two seasons for local amateur club
SV Muttenz. He then played six months for local club
FC Concordia Basel before he played six months for
FC Baden. With Baden he made nine appearances in the
Nationalliga B, scoring one goal. He then returned to Muttenz for another two seasons. For the season 2001–02 Schreiber transferred to
FC Concordia Basel. He played as regular in their team and had teammates such as
Arjan Peço and
Marco Streller. Schreiber played 19 games, scoring three goals, one on 28 July against
SR Delémont and two on 31 August against
Kriens. Despite a mediocre first stage of the season, in the second stage the team was able to avoid relegation. Following his season with Concordia, Schreiber decided to reduce his football and moved on to local amateur club FC Gelterkinden. He later became coach. ==Private life==
