There was indeed a case for optimism for the Old Trafford faithful back in August when the season started.
Jose Mourinho had an impressive track record of winning the league title in his second year at every club he has managed and thus the onus was on him to deliver the coveted trophy in 10 month's time.
However, things were not straightforward and despite a brilliant start to the campaign, United's season derailed due to many reasons.
One primary reason for the same was Mourinho's inability to field a regular centre-back pairing as almost all of their defenders have been in and out of the treatment table throughout the season.
Thus, he is almost certain to bring in a quality central defender ahead of the next season and as a result, they have been linked with a host of names including Tottenham Hotspur captain Toby Alderweireld.
We look at 3 reasons why the Belgian will be a perfect addition to Manchester United:
#3 Proven and established
It is always a huge plus to have an experienced and proven defender in your rank as they bring a sense of tactical know-how when the situation demands.
United have conceded many goals due to rookie mistakes from their defenders this season and it is a problem Mourinho must fix as soon as possible.
Every top team in Europe has an established defender at the heart of their defence- Sergio Ramos, Gerard Pique, Thiago Silva, Mats Hummels, Vincent Kompany etc. and it is an absolute necessity if teams want to contest for Europe's elite trophies.
At the moment, it's fair to say that no United defender can be classified in the same rank as the aforementioned players.
Alderweireld is one such player who can bring a world of difference to United's current back-line and is capable of inspiring his fellow defenders and ease the pressure off them.
Plus he is accustomed to the physical demands and the ferocity of English football and thus can settle into life at the club with ease.
