Celtic and Southampton have reportedly agreed a fee to send defender Virgil van Dijk to St Mary's on transfer deadline day.
The Dutchman has been linked with a move to the Saints throughout the transfer window, but was thought to be keen to wait to see if the Scottish champions could reach the group stage of the Champions League before moving on.
BBC Sport reports that the Premier League side have agreed to pay £11.5m for the 24-year-old, who will sign a five-year contract if he passes a medical this afternoon.
Van Dijk joined Celtic in 2013 from Groningen, winning two league titles with the Hoops.
