Not finding a better place to put this response and not wanting to start a new thread, I'll just use this Mourinho's Utd thread.
In world football, it's my opinion that the highest performing clubs are the ones with a mix of world class talent and talent that is supportive to those world class players AND that the core players have played together for a number of years. We occasionally see exceptions to this rule but generally if you look at Barcelona's success with the players from the academy (not making a case to be an academy club btw...) or if you look at Real madrid, OR Bayern Munich, Juve... all of these teams have a significant number of staples that have been there for a long time.
As I get excited about new players, I do believe some significant improvements can be made to a club like ours to bring us to or near the top of the EPL (and I believe we are actively making those.... with top marks to the Glazers and Woodward) but to expect truly special football that can compete on the highest European levels, I believe that will only come with time. I think if Mourinho brings in 5 or 6 players that are near world class, I think we could expect the club to begin to compete with the likes of Madrid or Bayern within 2 or 3 years as they gel together as a squad. Unfortunately, many clubs have to get lucky to get to this point because there is no patience with management these days. They need to be lucky with several fixtures to get results to keep the manager around long enough even if he has a nice plan and foundation. If we can keep this core of players together for 3 or 4 years, I believe we'll be enjoying a run of trophy winning that could last a while. With DDG, Smalling, Shaw, Pogba??, Martial, Rashford, MK, that is a strong core that can certainly last 5+ years and be complimented year to year with additional talent that can help achieve on the highest levels but this group will need time.
Under Fergie, we were great for a long time and for a lot of reasons.... but not the least of those was the core group of players that played well together for a long period of time. Look at Leicester City, look at Bayern Munich probably the best example. Those guys play together adding a piece or 2 each year as the BFS of the world age out of their team. For pete's sake, they are basically the German national team too. No wonder they are like clock work.
To my ultimate point. There was no bigger hater of Mourinho that me. I hated Chelsea, Hate their owner and hated all the antics Mourinho and Costa pulled. I loved hating them. BUT, I'll now admit that I'm as excited as the next guy with the swagger he brings and the open purse that the owners and Woodward have given Jose to craft the core of his club. The football these guys played in the first game was enjoyable to watch (Depay aside) and it's aggressive attacking possession football. For me, that's the United way and frankly, that's the way forward beyond the foundation that LVG established.
And let me go on record as saying I DON'T CARE HOW MUCH WE PAY FOR PLAYERS. The market is different today. No argument can change my mind on that one. Pogba for 120 million, Martial for 30 million, shaw for 26 million, blah blah blah. Qualify under the FFP and spend to get that solid core (which we are).
