Barcelona youth sporting director Patrick Kluivert admits there's some frustration losing Takefusa Kubo.
The former Barca junior returned to Europe this summer to sign with Real Madrid before being loaned for the season at Real Mallorca.
The teenage attacker already has his first goal for Mallorca and is fulfilling his promise in the Primera Division.
Kluivert lamented: "When a player leaves your club, it's always a shame.
"But I hope he can succeed as a footballer..."
