Toulouse midfielder Jimmy Durmaz feels AIK superkid Alexander Isak needs to think carefully in terms of his management.
Isak, 17, is being linked with the likes of Liverpool, Bayern Munich and Real Madrid after a sensational start to the season.
For the moment, Isak has no agent and his affairs are being handled by older brother Sened Teame.
Durmaz told Fotbollskanalen: "I understand that the young man's brother wants to protect him. You want to work with all agents, why should you lock yourself into one?
"At the same time, I have been out for a while now, and if you work that way the risk is very high that there is not much happening. You should try to stick to an agent you trust and run with him."
