Glasgow Rangers boss Mark Warburton managed to get the 33-year-old to join the Ibrox side.
Noel Hunt has admitted that he still cannot believe that Rangers managed to pull off a deal to sign Joey Barton as he believed that the midfielder was destined for the Premier League next season, the Daily Record reports.
Despite proving instrumental in leading Burnley back to the top flight, the 33-year-old has turned his back on England by agreeing to become part of Mark Warburton's squad as they prepare for their Scottish Premiership return.
And the Irishman conceded that he is still surprised that Barton - who, he is convinced, will prove to be an excellent acquisition - has joined the Light Blues, but also insisted that he was delighted to see that the Old Firm were capable of attracting players of his calibre.
"He's going to shake things up, not because of his media work, more because of his football. He's a brilliant player and that's a real statement of intent from Rangers, he's a fantastic signing," he told the Record.
"I still can't believe it, to be honest. I thought he'd go back to the English Premier League but credit to him, he's gone to a massive club.
"And that's the thing about these two clubs - they don't need selling to anyone."
Although the Premier League may perhaps be the more financially lucrative option, the one-time England international has reached a stage of his career where he is unlikely to be playing for a side that will be continually battling for trophies.
However, the Gers showed last season that they are already capable of battling for silverware on several fronts. And while they will face a much tougher league campaign next season, their run in this past season's Scottish Cup - where they knocked out three teams from the division above on their way to the final - suggested that they had the quality to compete at the highest level even before they had made any summer signings.
And with Barton hinting during his time with the Clarets that he was not far from his best this past season, it appears that he could be battling for plenty of trophies during his time with Rangers.
