Now he is a FIFA referee, Stephan Klossner probably has to take it easy on his day job at the Berne University doing research into "the effects of mechnical stress on skeletal muscle and the muscle hypertrophy response".
Stephan Klossner starts as a UEFA category 3 ref.
for a start
The two 2012 European u19 elite group matches were his first serious international designations. In the first match Stephan showed 7 yellows and 5 in the second. But that second match must have been something: 3 direct reds for Romania and three penalties for the Serbs. And 41 fouls.
