Matthijs de Ligt would be a great acquisition for Manchester United or any of Europe's top clubs, according to former Denmark international Jesper Olsen.
De Ligt has been heavily linked with a move away from Ajax at the end of the season, following in the footsteps of Frenkie de Jong, who will join Barcelona in a €75m (£64.3m/$85.5m) deal this summer.
Barca, Juventus and United are all reportedly vying for De Ligt's signature, with Ole Gunnar Solskjaer thought to be keen to strengthen his defensive options for next season.
