4 signings that could turn Manchester United into Premier League title contenders next season

#1 Kalidou Koulibaly (Position - Defense)

United should go all out for Koulibaly

The current United team has been crying out for a defensive leader in the mould of Virgil van Dijk for quite sometime now. They have been badly affected due to their defensive frailties this season. As such, Solskjaer is on the lookout for a new central defender and his search should start and end with Koulibaly.

The Napoli defender has been in outstanding form this season once again. Koulibaly is a ball playing defender who is very good at passing and setting up play from deep. However, he is also very strong at the back and can bully any striker in the world on his day. Alongside Lindelof, Koulibaly would provide composure, steel and a whole lot of muscle in the back. And United would have two extremely capable ball-playing centre-backs in their ranks.

The Senegalese is also a goal threat from set pieces, where his giant frame can be a handful for any defensive unit. Koulibaly's presence at the back would settle the nerves at United and give the team the freedom to attack without fear.

The two factors that might concern this deal would be the age of the player and the cost of the transfer. Koulibaly will turn 28 in June and would cost United in excess of £90m. However, if United take the risk and invest in the Senegalese, they will be richly rewarded next season.
