Barcelona want to re-sign winger Dani Olmo three years after he transferred to Dinamo Zagreb, according to a report in Diario Sport.
Olmo joined Dinamo as part of the swap deal which saw Alen Halilovic move to Barca in 2015 and has since emerged as a star for the Croatian club.
The winger is now 20 and the report claims the Catalan club have now made contact over the future of the Spain Under-21 international.
Dinamo have previously knocked back interest from Valencia and Milan while Borussia Dortmund, Manchester United and Olympique de Marseille have also been linked.
However, the one stumbling block to any deal is Dinamo’s insistence that they will not sell their star for less than €25m.
