Five things I think Ruud van Nistelrooy interim spell has taught Ruben Amorim about Manchester United

Ruud van Nistelrooy will take interim charge of Manchester United twice more before Ruben Amorim officially begins work as the new head coach at the start of next week.

The 39-year-old insisted he did not watch as United defeated Leicester 5-2 in the Carabao Cup a week ago, but admitted he was one of the millions who tuned in for their draw with Chelsea at the weekend.

In reality, Amorim will have been doing plenty of research on United ahead of his arrival, and will have extensive knowledge of the environment he is walking into with huge expectations on his shoulders.

This is what he will have learned about the side from their two matches under interim Van Nistelrooy:

There is not a natural goalscorer in the side

United might have scored six goals in their two matches under Van Nistelrooy, but not a single one of them was scored by a striker. Joshua Zirkzee has faced the majority of the criticism for their bluntness in front of goal, though Rasmus Hojlund is just as much to blame.

A lot has been made of Viktor Gyökeres's success under Amorim at Sporting and how he can bring the best out of the United forward's, yet on recent evidence, there is little to suggest a drastic change is imminent. The new head coach will have to work with what he has got for now, but in the long run it still feels like they need another striker signed.

Players are lacking confidence and making bad decisions

United's poor decision making went largely unnoticed against Leicester before it was amplified to the extreme against Chelsea. Their latest performance was littered with individual errors and it was clear that a number of players are lacking confidence after such a tough start to the season.

So much focus has been on the formation change Amorim could implement at Old Trafford, but one of the other big challenges for him will be to restore the confidence that is lacking at the moment.

Manuel Ugarte is becoming a problem

It looked liked Ugarte had turned a corner two weeks ago, instead he has gone full circle and is back where he started. The Uruguayan was particularly poor against Chelsea at the weekend and there will be huge pressure on Amorim to get the best out of a player who he already knows so well.

While there is an exception that the new head coach is working with a squad shaped by Ten Hag, there is less excuse if Ugarte doesn't enjoy an improvement under the man who made him a star at Sporting.

Key players need to be dropped

With the expectation of a formation change comes the consequence that some key players will need to be dropped. If United do switch to a 3-4-3 approach, then at least one midfielder will need to be benched, and if Bruno Fernandes is used as one of the support options in attack, then one of the wingers will come out of the side as well.

There is plenty of reason to be excited by the proposed change in tactics, but right now it doesn't feel like the personnel suit the suggested system.

This is not a quick fix

It was easy to get carried away by the nature of United's win over Leicester, but they could quite have easily won just as comfortably had Ten Hag been in charge against such poor opposition. The draw with Chelsea was a fairer reflection of where United are at and a reminder of just how much work needs to be done until they are one of the top sides in the Premier League themselves. Amorim is an exciting appointment, though it would be unfair to expect a quick fix.
