#2 Harry Maguire or #3 Toby Alderweireld or #4 Yerry Mina
The best options for a centre-back pairing are Eric Bailly and Victor Lindelof as time should end for Jones and Smalling, whose errors cost so many matches for Man Utd. If not for the presence of De Gea, it could have been even worse.
Lindelof has been overlooked by Mourinho last season and that could probably change after his performances in the World Cup. Bailly was out most of last season due to injuries. This means the team has no settled or reliable back-pair and they need someone with a commanding figure and who posses an aerial threat during set-pieces that have been missing since the departures of Rio Ferdinand and Nemanja Vidic.
So, United are definitely going to sign a centre-back we are going to analyze about players who are strongly linked to the team.
Harry Maguire
Harry Maguire has been linked to Manchester United, according to reports. It is understandable that Leicester don't want to lose another star player to Manchester. Leicester City are demanding more than £65 million to make United change their stance.
Let us see what he brings to the team:
With a towering 6'4" frame and a breezeblock-sized forehead, he is the type of player strikers will fear to battle against. He can be an immense threat while moving forward during set-pieces, which we all saw how good he can be at setpieces during England's game against Sweden.
What are the drawbacks?
Harry Maguire had a good World Cup and he is a good player, but the performances in the World Cup were not against any top teams, which is a notable point.
He might bring some aerial threats to the team during corners and he is good on the ball, but he doesn't improve the squad majorly and he is of a similar kind of player like Phil Jones during his early days.
The money Leicester City are asking is a bit too much and we think spending more than £65 million on him is not a good idea, rather they can look at other options.
Toby Alderweireld
Toby Alderwiereld was another player Manchester United are considering signing, according to reports.
It is understandable that Tottenham Chairman Daniel Levy wants in excess of £50 million for a player who only has one year left in his contract with a £25 million release clause and a one-year extension of the contract.
What can Manchester United get from Toby?
He is an established Premier League player, who has done well with Tottenham and gained experience. He is good on the ball and in the air and doesn't lose composure even at difficult times that we saw in the recent World Cup with Belgium.
What are the drawbacks?
The first thing is the asking price, as it seems United are reluctant to pay anything over £50 million. It is not worth spending that much money on a player who is nearing his 30's, which means not many fruitful years are ahead of him.
Yerry Mina
New reports suggest that Yerry Mina was an alternative option for Manchester United. Let us see what he brings to the team and whether they should buy him or not.
Yerry Mina joined Barcelona in the January transfer window but could be sold due to the number of non-European players limit in La Liga. His valuation was around the £25 million and he is probably Man Utd's best option in terms of money concerns.
What are his strengths?
Mina is 6'4'' and a powerful defender. He can play the ball from the back and he is an excellent option for attack during corners too as he is strong aerially. It was perfectly demonstrated when he scored three goals in the recent World Cup, with all the goals coming from his head. He is a weapon to have during corners, which is a tempting point for Mourinho to sign him.
Does he have any weak areas?
He is not fast on the ball, which could be a worry for the Premier League style of play. His anticipation and position are bad at times and to rectify it, he makes some tackles that could end his game that day.
Considering his age as he is only 23 years, he can develop into a good player in the coming days. Besides, his price is also affordable. Manchester United have a chance to sign the Colombian international if they are priced out for other players mentioned.
