Center-back: Victor Lindelof and Kalidou Koulibaly
Victor Lindelof has become a regular under Ole Gunnar Solskjaer and the Swedish international will be an important player for United in the coming days. He has shown good form and performed well in the opportunities that he was given with. Hence, Lindelof will be one of the defenders who will be a constant starter next season.
Manchester United have earmarked Kalidou Koulibaly as a prime-target this summer and the Red Devils are ready to splash for the Napoli defender. The player is a target for top European clubs and hence, United has to make an early move to sign him.
Manchester United has leaked a lot of goals this season after they failed in signing a center-back last summer. Hence, a defensive signing is a priority before the next season and based on the skills and performance, Koulibaly has to be that signing.
