They sure do have a lot of 'stars' in their squad and the manager himself is a big star. But their form as of late has been so abysmal and their 'star' players' performance so average that I can imagine Jose Mourinho getting a quote from a Tom Cruise movie but is actually looking like this...
Jose mourinho is the reason that the team is not complete. He lacks of strategy, to be honest I dont really likes how he handle the team. He relies more on defensive and counterattack strategy while manchester united's team squad is not really suitable to use that kind of strategy
I agree with some of what you're saying but blaming Mourinho entirely for United's demise is totally not correct imho. There's already something with the club on why it has been under-performing since Ferguson left. As I have said over and over in this thread, what United needs is to suck it up and accept the fact that their era is gone. From there they can make a total revamp of the team and start from scratch. It would be easier for a manager to work with a new set of players than working with the sickness of the present one.
