Dani Olmo left Barcelona for Dinamo Zagreb when he was 16 and was recently in the final 20 for the Golden Boy award.
The midfielder is also in the Spain U21 squad and has been linked with a return to Spain at some point.
Olmo says he is happy in Croatia but he does not rule out a return to his homeland -- or Barça -- at some point in the future.
"Of course I still follow Barcelona and whenever a teammate like [Carles] Aleña comes on I'm really happy," Olmo told Diario SPORT.
"They're doing really well this season. They have a team full of talent. Many world class players. Barça are always Barça.
"I don't regret leaving, it was the toughest decision I have taken because I was leaving one of the best clubs clubs in the world, but I'm happy, I have adapted well.
"Barça is a team that I will always carry inside me. I played there for seven years and I have a special affection for the club so why not [return one day], I would like to but we will see what the future holds.
"They're one of the best clubs in the world. Who would not want to weat the Barça shirt. I am not closing any door on Barça or any other club right now.
"But I don't get involved in subjects to do with my future, it's for my agent and my father. It doesn't inerest me that much, either. I am focused on playing fooball."
