The Hoops have been told the Croatian Under-20 international is valued at £4million by his club.
The SPFL champions have an interest in the 21-year-old centre-half as they prepare for the likelihood of Van Dijk’s departure. They have not made a formal offer, but they have been told Dinamo will not contemplate selling the classy back-four operator for anything less than what they consider the going rate.
Deila insists there is no prospect of star defender Van Dijk leaving before the two-leg Champions League play-off with Sweden’s Malmo with the first leg in Glasgow on Wednesday and the return the following Tuesday.
Southampton and Everton are among a list of interested clubs pursuing the Dutchman, who cost £2.6million when he signed a four-year deal in June 2013 after arriving from Groningen. Celtic are set to achieve a Scottish record fee of around £15million should they decide to cash in on the hugely impressive Van Dijk in this window.
