#2 Matthijs de Ligt - Ajax
With Barcelona already making their moves in order to secure the Dutchmen's signature, de Ligt has been linked with the Blaugrana for an extremely long time. The young centre-back is known particularly for his pace and hard-hitting tackles from any defensive position. The €50 million defender can be of some use to Maurizio Sarri in the future, as pace and consistency as a defender are what de Ligt truly offers.
At just 19 years old, he can be a long-term replacement for Luiz and can take his place offering utmost efficiency as a defender. One of the key factors here is that the Ajax star is already linked to some of the most prestigious clubs in Europe and can possibly move somewhere else. However, Chelsea will have to step up and offer an extremely hefty sum in order to secure his signature.
