George Edmundson underwent his Rangers medical on Thursday and is expected to sign a deal before joining the Gers on their pre-season trip to Portugal.
The in-demand Oldham defender looks set to become Steven Gerrard 's sixth summer signing after a fee of £650,000 was accepted by the Boundary Park club.
Edmundson had also been the subject of bids from Peterborough and Portsmouth while Stoke, Hull and Preston were also said to be monitoring his situation.
But after having two bids turfed out by Oldham it was third time lucky for Gers with the player keen to join up with Gerrard after being given the VIP treatment on a trip to Glasgow last month.
Edmundson will provide competition to Connor Goldson and Nikola Katic in the heart of defence following Joe Worrall's return to Nottingham Forest after a loan spell and Gareth McAuley's exit.
The aggressive defender was named in the League Two team of the year after a dominant campaign with the Latics.
He made 52 appearances last season, scoring twice, and was hailed by former Oldham team mate and ex-St Johnstone winger Lee Croft.
Croft said: "He’s strong in the air, loves a tackle, but he’s came on a lot on the ball as well.
“He’s still only 21, which is young for centre backs, so there is a lot of potential there as well.
“To be honest, I thought he would have gone sooner as there has been a lot of talk about him for a good while.
“There was talk about Sunderland maybe 18 months ago and it was only a matter of time before he made the step up, whether it’s Rangers of anywhere else.
“He’s a big talent so not surprised he’s getting noticed.”
Edmundson is expected to be a Rangers player by the time Gerrard and his squad touch down in Portugal for their pre-season training camp at the weekend.
Joe Aribo could be next. The Charlton midfielder is meeting Addicks boss Lee Bowyer on Friday to decide once and for all on a new deal offer at the Championship club.
