Charlton midfielder Joe Aribo is due to have a medical at Rangers on Monday before completing his move to Ibrox this week.
The 22-year-old’s contract expires this summer and he told Lee Bowyer on Friday that he will quit Charlton to sign for Steven Gerrard's Rangers.
Charlton will only receive a fee of around £300,000 when Aribo makes a cross-border move.
The Addicks would have been due a much larger compensation package had Aribo stayed in England.
He attracted interest from Premier League and Championship clubs but decided to join Rangers ahead of their Old Firm rivals Celtic.
Bowyer had hoped to convince Aribo to sign a contract extension at Charlton when the pair met on Friday.
Aribo played a key role to help Charlton secure promotion from League One and his departure is a blow for Bowyer as he plans for life in the Championship.
The opportunity to play under former Liverpool captain Gerrard was a big factor behind Aribo’s decision to join Rangers.
After completing his medical, Aribo is expected to meet up with Gerrard and the Rangers squad at their pre-season training camp in Portugal on Tuesday.
Meanwhile, Charlton midfielder Jake Forster-Caskey has signed a new one-year contract.
The 25-year-old missed most of last season with a serious knee injury but is now fit again and has been handed a fresh deal.
