This would (probably) be true if Dinamo had squad similar to those that played EL and CL last 3-4 years.So going to the Conference League instead where allegedly Dinamo Zagreb is a titan and would be smashing everyone else was great.
However this is not the case this year. Lots of turbulence after winning the league title last year - changes/uncertainties in club leadership department, restricted budget or just plain bad planning and execution during few past transfer windows.
Following bad start of the season (both domestically and in UEFA) Dinamo sold several key players (national team goalkeeper, right winger, defender), continued with bad results and then completed some questionable transfers ad-hoc. Following injuries of some first squad players, coach change etc. there is obvious decline in quality.
Even though both media and fans had consensus that falling into Conference League was a failure, recent form and results (worst season start in past 20yrs) proves the point that Dinamo will struggle to pass this group. So this was a blessing in disguise as in EL we would see low point count for sure.
There is a lot of space for improvement - and that is the only positive thing at the moment.
Home game on Thursday against Viktoria will be key in decision if Dinamo will sack second coach this season; which in case of another loss (3 out of last 4 matches) will probably happen, even though issues are on different levels.
