I firmly believe the Glazers want to win things, they're just incompetent. You don't buy Varane, Sancho and Ronaldo after finishing second if you're content with top 4.
That depends on how you look at things. All three of those are very marketable, Ronaldo massively and yes, they will improve the team. They keep the fans happy which is invaluable and give us a better chance of keeping top 4. Would they like to win trophies? 100%. Do they care that much? I can't see how you can argue that they do when they have been so unwilling to put the structures in place to make it likely.
Every man and his dog has been saying that United need to improve in so many areas of how the club is run and the high ups have just not done it. If you are desperate for trophies then you do everything in your power to give yourself the best chance of doing that. You hire the best managers. You aggressively go after the best managers around and not just the ones that happen to be floating about when you get rid of your last one. You hire the best coaches. You play a modern style of football that allows you to compete with the best teams in the world and also beat the poor teams that only turn up to defend.
You constantly assess whether your current manager is up to the task and if there are better alternatives.
Nothing the glazers do suggest that they give too many monkeys about trophies. Its utterly bizarre because we could easily be as good as City and competing for trophies every season. We are as rich as the oil clubs for the most part and we are one of the biggest names in football. There is 0 excuse for our current predicament. We are not Arsenal. We are not a team that has eaten at the top table for years but is now trying to do the same while everyone around us is spending double what we can. No excuse.
