The club was completely stretched for cash flow in his final seasons.
This is the entire reason why we are where we are.
Failure to invest from 2009-14.
Bollocks. What about the investment from 2014 to present? I give you 15 good reasons (and $571 million US dollars per transfermarkt,) why the club is struggling. The reason is that Moyes, LVG and Jose decided to spend money on the likes of:
Fellaini, Mata, Rojo, Blind, Falcao, Di Maria, Darmian, Bastian, Schneiderlein, Depay, Bailly, Mkhitaryan, Lukaku, Matic and Alexis.
Failure to invest has never been the problem. The problem has been failure to invest PROPERLY!
You can't keep missing on signings, then blame lack of resources. United have just spent poorly. There are no two ways around that. United have spent more than enough the past 6 years to be competing for titles. To blame the current plight on lack of spending from 5-10 years ago is bonkers. United have spent over $1 billion US dollars on players since Fergie retired. $1 Billion! $1 Billion!! And people think the problem is lack of investment. City have only spent like $100mm more over that time period, and signed guys like Sterling, De Bruyne, Fernandinho, Sane, Jesus, Bernardo Silva, Walker, Ederson, Stones and Laporte.
You can blame alot of people-- but I'm pretty sure you can't blame SAF for the terrible signings of the past 6 years. (Comment directed at the OP, not you Minger.) I pretty much blame Moyes, LVG, Jose and Ed for these terrible signings. With some blame going to the Glazers for not moving Ed out of his current position for which he is so woefully underqualified. Actually, more blame on the Glazers, because even though they aren't football people-- they have to realize by now that Ed is borderline incompetent on all football matters. It was easy to be owners when SAF was running the show and making all the decisions, but now they need to put in the proper structure, which they haven't.
Nothing will change as long as they keep signing mediocre players and for way too much. Lets hope Ole has a better eye for talent than his predecessors.
