Celtic manager Ronny Deila insists Virgil van Dijk does not want to leave the Scottish Premiership leaders in January.
Celtic boss Ronny Deila says keeping his best players will take priority over acquisitions in the transfer window.
The 48-year-old tactician has been rewarded for the positive impact he has had since taking over at El Madrigal in January.
He helped secure promotion to the Primera Division and they currently sit fourth in the top flight after 13 games.
The former Levante man has also coached the likes of Sevilla and Racing Santander, and will now remain with the Yellow Submarine until the summer of 2016 at least.
