Maybe to see whether Manchester United can really be consistent or not, I think we have to look at Manchester United's match against Chelsea. This match will be held in two days, in my opinion this match will be very suitable to see whether Manchester United's performance will be consistent or not. Because if we look at the depth of the Manchester United and Chelsea squads, it could be said that the quality of the players is balanced.
Both clubs have many star players but general sentiment in Chelsea is better and more positive than in Manchester United with massive disappointment since the season beginning. In a first match as a temporary coach for Manchester United, Ruud van Nistelrooy helped them to win big and brought positive moment back but I doubt it is enough for Manchester United to beat Chelsea in this match. They are balanced on paper but on field, Chelsea are better in recent form and they will have better chance to win this match.
So of course this match will definitely be balanced if you look at the squad. Maybe if, for example, Manchester United could at least hold Chelsea to a draw in this match, this could be a sign that Manchester United is now truly rising from its downturn. But if, for example, Manchester United loses this match by at least 2 goals, it means that Manchester United still cannot be said to have recovered from its downturn.
A draw against Chelsea will be big success for Van Nistelrooy but he and Manchester United will hope that their honeymoon continues with another win. If Manchester United can tighten their midfield and defense areas, prevent Chelsea attacks, they will have some opportunities for a winning goal. They will have chances, just not too easy for beating Chelsea.
