No it isn´t. It is not even decent, because it has a serious lack of depth, not in numbers but in quality. You have one world class CM, who has carried huge weight in the last season for United and was the sole reason, why it was not the weakest area. The problem is, that you have no cover for him, which is looking at the season ahead of United simply mind blowing and will hopefully be fixed in the next weeks.
Who do you intend to play instead of Carrick, if he gets an injury? Nobody hopes for it, but you have to plan for that case. Anderson? Jones? That is simply not good enough going up against the top sides of the EPL or Europe, who are filled to the brink with players capable of ripping midfields apart, if you give them the room for it.
You could be nice and give us one or two of your midfielders...
