Man Utd are in trouble because their higher management have no plan and its a warning to Juventus to needs fix up. Despite all that money and superstar players, they have regressed massively. Management needs clear ideas and if you look at City and Liverpool, they planned to accommodate their managers and support them hence why they're both maintaining such high levels of football. Liverpool in particular are seeing their best and most prolonged period of success since those Ian Rush days. Of course money buys good players but money is easier to waste, Juventus are the perfect example of that.
