Jesper Olsen labelled Barcelona-bound Frenkie de Jong a "very special" player as the Ajax star prepares to team up with Lionel Messi at Camp Nou.
De Jong will move to La Liga champions Barca at the end of the season after agreeing a transfer worth €86million in total.
The 21-year-old midfielder attracted interest from Europe's biggest clubs, including French giants Paris Saint-Germain, before opting for Barca in January.
And ahead of Ajax's Champions League quarter-final first-leg showdown against Juventus in Amsterdam on Wednesday, former winger Olsen heaped praise on De Jong.
