I still believe we are two world-class players away from becoming a top team and
winning the league. That's the main issue.
Unfortunately, Di Maria did not work out, Rooney hasn't found his form, Mata has never been world class, Martial is still too young, Bastian is not as good as we hoped...
We currently don't have a single world class outfield player!
We need to spend another 150 million for two TOP players. And it is not easy to find them, even if we have the money. But at this point we need world class players to make the difference. Nothing else will lead us to trophies.
LVG is good enough. Sometimes, he may be doing questionable things (even stupid things) but who doesn't? Even SAF has done a lot of bizarre substitutions over the years. Any other manager will also do those, especially when the team does not play well. Most top managers will gamble when both Plan A and plan B (Fellaini) do not work.
