Go Ahead Eagles have been primed to expect an offer from Rangers for Finnish international winger Oliver Antman.
And the Dutch club are waiting to discover whether Celtic return for Jakob Breum after turning down three approaches for the Danish wide man from the SPFL champions.
Sheffield United have been heavily linked with a move for Antman, after the 23-year-old provided 15 assists in 32 league games during his first season in the Eredivisie.
Herald Sport understands, however, that Rangers have now taken a firm interest in the right sided attacker.

Signed last summer from Nordsjaelland, Go Ahead Eagles are looking for a fee in excess of £5million for one of the break out stars of Dutch football and have been told to prepare for an offer from Ibrox by intermediaries.
Russell Martin has already confirmed an interest in Crystal Palace winger Jesurun Rak-Sakyi, a player he tried to sign during his time at Southampton. Rangers have already submitted a loan offer with an obligation to buy for £8million.
Go Ahead, meanwhile, have already rejected a number of financial proposals from Celtic for Danish under-21 international Breum.
In the market for wide players after selling Nicholas Kuhn to Como for £17m and losing the services of the injured Jota until early next year, the Parkhead club opened with £1.5million last month.
Despite Celtic upping their original proposal to £1.75million plus add-ons, then putting £3million on the table, the Dutch Cup holders have placed a price tag of Euros 7.5million (£6.5million) on a player signed from Danish club Odense in the summer of 2023.
PSV placed Breum high on their shortlist of summer signings before deciding to pay £15million for AZ’s Ruben van Bommel instead. Claiming their valuation is fair and realistic senior figures inside Go Ahead maintain that the player will not be allowed to leave for a knockdown fee.
Celtic also have a long-term interest in Antwerp’s Belgian winger Michel-Ange Balikwisha.
