Rangers cannot compete with the wages on offer in England in their pursuit of Joey Barton, reports BBC Sport.
The midfielder has been heavily linked with a move to Rangers in recent weeks as they build ahead of next season.
He has already visited Ibrox to discuss terms over a deal, with Mark Warburton’s side now waiting to discover his next move.
The midfielder is likely to be a man in demand, having been a star performer for Burnley in a Championship winning campaign and making it into the Championship Team of the Year as a result.
The Clarets are keen to keep hold of him and Rangers boss Warburton has conceded that his side cannot compete with the wages on offer down south.
"Joey is a player that will have many, many suitors I'm sure," BBC Sport reports Warburton saying.
"If we can show what we are as a club - the support, history, stature - and our aspirations and targets then hopefully any player will find that appealing.
"We're never going to compete with wages down south, that's an obvious point to highlight.”
Barton would certainly represent something of a coup for Rangers ahead of next season in the Scottish Premiership.
Many are anticipating that they will compete with Celtic for the title next season, but they will need additions in their squad to do that.
It will be key that they add experience to their side, and Barton would add just that should they be able to secure his signature.
