Description: In general, Marco Fritz can be described as calm referee who is however very strict in situations when it is needed to be so. He does not refuse to show cards if necessary, he escaped bigger mistakes in the past. He was heavily pushed during the last years, after only two years as official DFB referee, he joined the 2nd Bundesliga pool of referees and mostly assisted Michael Kempter in Bundesliga as AR2. After only eight matches in 2nd Bundesliga (in 2008), he was directly taken on the Bundesliga list which was of course a surprise, but finally, it was nothing else than deserved.
