The 33-year-old has become the latest face to join Mark Warburton's revolution at Glasgow Rangers.
The 33-year-old has agreed a two-year deal with the Light Blues, The Scottish Sun reports, and after completing the switch, he confirmed that if money was the motivation behind his decision, he would have gone elsewhere.
"I had better financial offers - but you have to be able to look yourself in the mirror, and coming to Rangers allows me to do that," he told The Scottish Sun.
"I knew within an hour of setting foot in the building that this is the right place at the right time for me."
The fact that Barton was willing to reject better offers from a financial standpoint - The Scottish Sun claims that Burnley had put an offer on the table that would have seen him stay for their return to the Premier League - undoubtedly sends a major message out regarding how attractive a prospect Rangers is currently.
Getting a player of Barton's calibre on board - the one-time England international was one of the best players in the Championship this past season - may convince other targets that the Gers are pursuing that Mark Warburton is taking the club in one direction, and they can be a part of that.
And in return, Rangers can feel confident that they have completed a deal for a player that is promising total commitment to trying to help them get back towards the summit of the Scottish game, and perhaps re-establish the club on the European stage.
