Southampton and Sunderland remain in the hunt for Celtic defender Virgil van Dijk.

The Mirror says Saints boss Ronald Koeman and Black Cats chief Dick Advocaat have both had offers for their fellow Dutchman Van Dijk rejected by the Hoops.

Southampton had a bid of around £10million knocked back by the Scottish champions and were told the 24 year-old is not for sale.

Sunderland had a £6m offer turned down in January, but have continued to monitor Van Dijk's situation.

And Celtic now look set to soften their stance.
