Ajax defender Matthijs de Ligt cannot guarantee he will be in Amsterdam next season.
The teenage defender is a target for Arsenal and Barcelona ahead of the summer market.
De Ligt, after victory over Heracles Almelo, said: "Whether I can reassure the Ajax fans? No, it is very difficult.
"I would like to reassure the supporters, but the football world is strange. I really do not know and I cannot say anything about it."
De Ligt, 18, captained Ajax for the Heracles Almelo win.
