How Manchester United lost their ambition?

Manchester United have not won the league in 6 years. Let that sink in folks. The Glazers are owners that are only driven by increasing their profit margins rather than winning trophies. A creative midfielder and a right-winger were needed at the club but through their henchman, Ed Woodward this wasn't forthcoming.  The Glazers must realize that if the team continues to perform poorly on the field, sponsors will pull out and the profit margins that they value so much will be diminished drastically. It doesn't matter if Pep comes to manage just like previous managers won't be backed in the transfer market. I have issues with Ed Woodward as C.E.O. but he is not to be blamed for poor buying in the transfer market because he doesn't have the experience of dealing with football agents and clubs. Even if he is removed from his post how do we know that the owners won't hire somebody similar to Ed Woodward? The Glazers need to change their mindset from making money to winning trophies which should be the goal of Manchester United. If they can't there will be a long goodbye for themselves.
