Absolutely nothing wrong with having ambition, but you need to back it up. Don't say you're going to be a doctor and then drop out of school, don't say you're going to lose 5 stone and then go to mcdonalds every day, don't say you're aiming to win the league and then sign mediocre players. Words are easy, actions are not. So far Moshiri has said a lot and done very little when it comes to our ambitions.
Lovely analogies, but what does that have to do with Moshiri ? He supplies the cash, which he has done, the managers, DOF's and the scouts choose the players to spend it on. Maybe you should be directing your ire at them.
Tbh Brands and Silva have in my humble opinion bought some really good players in, they may just need some time to gel and may even need another transfer window or two to get more of their targets in and also more of the previous dross out.
Again it takes time and patience, I used to prefer my coffee instant, perhaps like you, now I prefer a Latte, it takes a bit longer to make but it tastes much better when it's done.
