Virgil van Dijk has reportedly sought a transfer from Celtic.
The Daily Express says Van Dijk has rocked Celtic by telling them he wants to leave.
The Dutch defender is being tracked by a host of clubs, including Sunderland, Newcastle United and Hamburg, and has told manager Ronny Deila he wants to go before the close of the window.
Deila and the club are desperate to keep the former Groningen star but the player is adamant he wants out after their Champions League exit.
