If Manchester United would prefer a younger option to improve their defence this summer, then Nikola Milenkovic is the man they should be looking at.
Milenkovic rose to prominence for Fiorentina this season and is now regarded as one of the best young centre backs in world football.
The Serbian is quick, a strong tackler and, most importantly, can organise a backline. The latter is definitely something that United need.
Fiorentina would demand a significant fee for their young star, but United should be willing to pay that for the man labelled as the next Vidic.
