#2 Kalidou Koulibaly to Manchester United
Manchester United have been a revelation under the stewardship of Ole Gunnar Solskjaer. Attacking, exciting football has made its way back to Old Trafford. This sudden change of fortunes has definitely gotten the fans excited.
Something that still remains an issue though is the leaky backline. The team can't always depend on David de Gea to bail them out every time the centre-backs make basic mistakes. Moreover, when they face elite opposition with world class players, even de Gea won't be able to bail them out.
Kalidou Koulibaly is the answer to this problem. A tall, strong, ball playing centre back would make Manchester United genuine title contenders for next season. His ability to carry the ball out of defence would mean the entire team could push up and play with a higher line. This would see the likes of Pogba, Rashford, Martial and Lingard receive balls in dangerous areas of the field and be more direct with their possession.
It would take United a world record bid to tempt the Partenopei chiefs to let one of their best players leave.
