The Scottish giants have turned their attention back to Juranovic after failing to convince Manchester City starlet Yan Couto to agree to a loan move to Glasgow.
They have already seen a bid for Juranovic rejected by Legia Warsaw, but according to Polish outlet Sportowe Fakty, the Bhoys are expected to make another offer.
It is claimed that Celtic’s first offer for the Croatian was higher than the £2m that they were suggested to have bid.
Talks between the two clubs are continuing as Celtic look to take Juranovic to Scotland.
It has been claimed that Legia Warsaw are looking for a fee of £3m in order to let the player move on this summer.
Celtic have made signing another right-back a priority as Ange Postecoglou looks to continue adding to his squad before the transfer window slams shut at the end of the month.
Juranovic has been capped by Croatia at international level on ten occasions and joined Legia Warsaw last year.
