Ineos/Ratcliffe is an investor. Nice is an investment. A investor has a goal with every investment. A business plan. Broadly, given the sums Ineos has invested in Nice -- I can have no objections against Nice's performance. I would have been more worried had Ineos pumped 500m into Nice to compete with PSG and they had failed. Their net spend on transfers the last 3 years is about 75m. For a club spending in the range of Lille, the Ligue 1 is not a walk in the park. Besides PSG you have Monaco, Marseille, and Olympic Lyon and a bunch of fairly well run club with good youth organizations. Its like someone takes over Crystal Palace and give them 50m extra transfer fees each year. Sure they should improve, but its not like you can guarantee to finish no worse than 7 in the PL every year. Reasonably, some years should be better, some years worse.
If Ineos had invested much more than it have in Nice -- would that have been better? Honestly, would not that be pretty dumb? Sure, there are money to make for a club that is very successful on the pitch -- but if you as an investor were interested in pumping 200m into a football club -- why on earth would you pick OGC Nice? I do not know what Ineos business plan is for its investment in OGC Nice. But the fact alone that it is a tiny Ligue 1 club tells me that its intentions has not been to compete toe to toe with PSG. If its to build up the club properly and to get into a position were you can compete for top 4 spots, become a steady top 3-5 club in Ligue 1, it seems like they are heading in the right direction from the perspective of the size of the funds made available to the club. Ultimately, it will be up to the executive management of the club to make use of those funds. A journey like this is never straight.
I am not saying that Ratcliffe would be a great or horrible owner of MUFC, or something inbetween, I don't know. But I am not worried looking at Nice. If anything, it seems like their approach is quite sensible. Another approach would to throw a lot of money at the club early, -- but like we all know, that can work but it can also fail. Having a long term approach is definitely not wrong.
