Celtic have had their offers for Gary Mackay-Steven and Stuart Armstrong accepted by Dundee United, with the two players undergoing medicals this evening.
Mackay-Steven has already signed a pre-contract agreement with the Hoops, but they have offered £250,000 to bring him to the club before the end of the transfer window.
Armstrong will also make the move to Glasgow, with the value of the deal coming to £2m plus add-ons.
The two players could face their former club when Celtic and United meet in the final of the Scottish League Cup.
