It's been a somewhat rocky start for the Red Devils under Ruben Amorim who arrived at Old Trafford back in November.
The coach's 3-4-2-1 formation is clearly taking time to get used to for all players and it's likely in the summer that there will be some sort of clear out. However, what about now?
The January transfer window has been open for just over a week now and even though it hasn't been the busiest of windows in recent years for Manchester United, this one could be vital for the rest of the season.
One of the biggest January signings for Manchester United in the last 10 years or so was Bruno Fernandes who is of course now club captain at the Theatre of Dreams.
The impact he had on the squad in the second half of the 2019/20 season was huge and it is something United should be looking at repeating.
Here are four players Manchester United could sign.
. Viktor Gyokeres - Sporting CP
The first player on this list won't come as a shock for many as Sporting's Swedish striker was linked with the club even before Amorim arrived in Manchester.
Gyokeres does have experience playing in a 3-4-2-1 formation having starred in Amorim's formation when the United boss was at the club.
The Swede first caught the attention of the football world when he played up top for Coventry City in the 22/23 season when they suffered a play off final defeat to Luton Town.
However, Gyokeres is certainly going to be the most expensive player on this list and if United are going to make any signings this month, they will have to sell some with the stand out being Marcus Rashford.
Real Madrid and Bayern Munich are also currently linked with Gyokeres.
Nuno Mendes - Paris St Germain
The PSG and Portuguese left-back has worked under Amorim before when the United boss handed him his first team debut in June 2020 while they were both at Sporting.
In recent days, it has been reported in France that Mendes has rejected a new contract at PSG and is interested in joining Manchester United.
This is the sort of left-back the Red Devils need. Luke Shaw is very injury-prone and is out at the moment with Tyrell Malacia also prone to injury after just coming back from a lengthy spell on the sidelines. He will also fit the formation.
It has also been reported that PSG won't let Mendes leave during this window but with the left back out of contract next year, the French side really need to act if they want to keep him.
Will Mendes cross the channel to join his old boss at Manchester United?
Milos Kerkez - AFC Bournemouth
Arguably, one of the most impressive left-backs in the Premier League over the last couple of years. Surely, the Hungarian won't stay at Bournemouth?
Just like Mendes, Milos Kerkez is another full-back who will fit Amorim's system.
There is probably a bigger chance of Kerkez leaving the south coast in the summer but he is definitely one to watch if he is to exit.
Liverpool are also known to be interested in signing the 21-year-old.
With potentially Kerkez and Mendes at Old Trafford by next season, it would add a lot of depth to the Red Devils in that position.
Matheus Cunha - Wolverhampton Wanderers
Like Kerkez, Cunha might be expected to leave the Black Country in the summer more than this month but Man United are interested.
Cunha would fit in nicely behind on the left of whoever is playing up top for the Reds and would surely shine when given the chance.
Wolves are in the relegation battle in the Premier League but despite rumours, he has reportedly verbally agreed a new deal to stay at Molineux under new manager Vitor Pereira
Arsenal are also after the Brazilian so the question is now, will he leave or stay?
