Just doing some reading up on Wicky (from wiki).
This stood out to me
"He became first-team manager on 21 April 2017, replacing Urs Fischer after a boardroom change.[18] Days later, the team wrapped up an eighth consecutive league title,[19] and on 25 May won the Swiss Cup with a 3–0 victory over Sion at the Stade de Genève."
This was his first senior team manager role, which was on coat tails of Urs Fishers success,
then at end of the very next season
"On 26 July 2018, having finished as runner-up in the domestic league and having been eliminated in the semifinal of the cup as well as having started the new season poorly, with elimination by PAOK in the 2nd qualifying round of the Champions League, he was dismissed"
Yes its 2nd in the league and a cup semifinal but this was in Switzerland with a team that did the double the previous season remember,
He then goes off the the US u17s and then to Chicago fire and gets chopped before returning to Switzerland and lasted a season and half at Young boys.
It sounds to me like he has been fortunate to land jobs with big fish in the little swiss pond but failed to maintain what was there before him.
Interesting that Urs Fishers name is in there as a success and he is apparently now an outside bet.
