Good trophy count yes but he's really messed us up for years going forward in ways that are proving very difficult to recover from.
You have trade-offs. With situation of our golden generation getting older, trade-off is either a) take maximum of out them and then have more difficult period later trying replace world-class players in entire lineup or b) bring in youth, try to merge with older guys, but with youth you will always have risks and you will usually end up being less successful.
What Lucho and board did and are still doing is more or less focusing on the first one. Buying people in their prime to give maximum support for Messi as long as he is still here. Not necessarily the right players, but logic is there. So it is really up to you if you prefer having 9 trophies in 3 years and 1 trophy in next 3, or getting 1-2 each year. The final result in trophy count may be the same, but the euphoria in treble never happens and in reality you always lose majority of competitions each year.
I think this comes down to personal opinion.
