Four center backs which can make Manchester United defense invincible

Well summer transfer window is going to open and now clubs have option to improve their weakest side by signing the best player from all over the world. Last season all the big clubs of Premier League have spent lots of money on signing the best players and we have seen the effect of these signings which made Premier League matches more interesting. Specially the race of top four positions in Premier League was really interesting this season and the tug of war between Manchester City and Liverpool was the best thing this season.

2018-19 season has not been good for Manchester United. They knocked out by PSG in the  Champions League. Manchester United finished at sixth place in the Premier League table. After such a disappointed season, Solskjaer would not like to repeat this kind of season again.

Manchster United is already involved in transfer talk with few of the best young talented players. Daniel James from Swansea FC and Sean from Newcastle FC are on the list of Manchester United. This season the weakest part of Manchester United was defense, specially central defense. The defense squad of Manchester United such as Phil Jones, Antonio Valencia and Young could not perform well this season. 

The only defender which performed consistently was Victor Lindelof but he was also struggling due to the absence of a suitable partner in the defense. Now since the season is over and we will have to look forward. Manchester United will have to bring world best talent in their defensive squad specially Central defender. Here are four world best defender which are available signing and can make Manchester United squad invincible.

4.   Samuel Umtiti:

Samuel Umtiti can be a suitable transfer target for Manchester United in this summer transfer window. Since Barcelona is involved in transfer talk with Ajax young talent De Ligt and De Ligt is interested to move in Barcelona. So if Barcelona signed De Ligt then they will have to sell Umtiti. Umtiti has an amazing passes accuracy of  about 94% in Barcelona and if Manchester United signed Umtiti then  Lindelof and Umtiti can make a perfect defensive partner in  Manchester United.

3.    Harry Maguire:

Last season Manchester United was interested in Harry Maguire but the deal could not be completed.  Manchester United is still interested in 26 years old center back. Manchester United rival Manchester City is also interested in Maguire but it looks like Maguire will prefer United over City because in United he has chances to get thee major role but in City his career will be under the shadow of other center backs. 

On the other side Leicester has no intention to sell Maguire this season but the center back will not stay in Leicester at the same old deal. If Leicester does not increase the wages of the canter back then he will has to chose one between City and United. if  Maguire comes to Old Trafford then it will strengthen the defense of Reds and he will make a good defensive pair with Lindelof.

2. Toby Alderweireld:

Manchester United has an other option which is the better choice for the Reds. Tottenham's center back Toby Alderweireld is the most experience and less expensive defender available for Manchester United. Toby has release clause of about  £25 million which is a bit cheaper for Manchester United. Old Traford is not the only one who are interested in Toby. 

Toby has been one of the best defender of English clubs in last few seasons. He has experience and he helped Tottenham Hotspurs significantly in the Premier League. Toby Alderweireld is young but calm and well composed player and a young United side needs this kind of experienced defender in their squad. 

1. Kalidou Koulibaly:

The number one defensive target for Manchester United is Napoli's Kalidou Koulibaly. Kaulibaly is one of the best defenders in the club football right now. He is absolutely unbeaten is the air with 1.95m height. He has stunning vision in defense and creates accurate tackles. He has more successful tackles then any other center back. Right now he is at the peek of his career and transfer for him to the Old Trafford will be a great addition in his football career. His release clause is very high for a defender  and Manchester United will has to pay a high amount if they want Koulibaly in their defense.
