It's undeniable that something like that has to be done and it's proven that they can be solid even without players being used as benchmarks or having big names.
Over time, Union's performance has improved and that deserves appreciation, even though I really wouldn't expect too much for the Champions League, but at least in this case they have reached a position where not many can even do it, which is very good for them.
UNion Berlin managed to become a team that deserves to be considered to re-enliven competition in the Bundesliga, how their performance this season was very good, yes, even though they had to experience several setbacks which caused them to be content with only being ranked 4th. But despite all that, we can't say that UNIon Berlin hasn't done well with what they've done this season. They have to make improvements in several positions to make their team even more solid.
Their conditions, with all the limitations in terms of resources and players, really expect consistency for one season, of course it will be very difficult.
But even so, still this has been very good for them regardless of some of the inconsistencies that occurred in a few games towards the end of this season it has also been very good for them.
Btw I'm interested in getting back to Leipzig now, they are currently missing 2 of their pillar players Nkuku who went to Chelsea and Konrad Laimer who moved to Bayern. It's sure to be another shakeup for them.
