Dani Olmo's proposed transfer to Milan is being held up by the player's agent demanding a hefty amount of commision, as well as concerns over a sell-on fee that Dinamo Zagreb are keen to have inserted into the deal.
Olmo surprisingly signed for Dinamo when he was 16 back in 2014, despite being tipped for success at boyhood club Barcelona. Since then, the versatile Spaniard has played just shy of 125 games for the Croatian side in all competitions.
Olmo appeared in each of Dinamo's Champions League group games this season, scoring against Manchester City in a 4-1 defeat in December.
Olmo is the latest in a long line of players to be linked with a January move to Milan, with Zlatan Ibrahimovic, Asmir Begovic and Simon Kjaer all arriving at San Siro already this month.
There has also been speculation regarding the club's interest in Roma winger Cengiz Under, with the player's agent understood to have travelled to Milan for talks over a move. However, I Giallorossi have not yet decided whether they would be willing to depart with the Turkish international.
