Ajax are demanding big money for Barcelona target Donny van de Beek.

The Dutch club don't want to let any more of their star players leave and would demand at least €55m to let van de Beek go, says Sport.

This isn't the first time Barça have made a move for Van de Beek. Ramon Planes had the midfielder on his list of options last summer but because the club failed to move anyone on, adding an extra body was impossible.

Ajax and Barça have a good working relationship but it appears any move for van de Beek won't happen until September at the earliest. Barça have other options on the table should a transfer not materialise.
