Speaking to the Scotsman, Rangers legend John Brown has claimed that his friends described Joey Barton as a "headcase" after he joined the Ibrox club.
Rangers pulled off the high-profile coup for the 33-year-old last month, signing him on a Bosman after his contract with Burnley expired.
The veteran midfielder had only spent a year at Turf Moor but his influence and experience helped the Clarets seal promotion straight back to the Premier League by winning the Championship title.
That being said, the former Newcastle United and Manchester City does have history when it comes to unsavoury incidents, though many of these came in his younger days.
The new Rangers man seems a much calmer figure these days, often making headlines for the right reasons, and Brown, who spent nine years with the Gers, is confident that he will be a success with the Glasgow giants.
“When Joey signed, a few of my mates phoned me to say ‘he’s a headcase’, said Brown to the Scotsman. “I told them that’s just through social media – he’s a good footballer and you just need to look at the clubs that he’s played for.
“He’s looked after himself, he’s a very good player and you can’t get enough of them. If you’ve got good experience in the spine of your side, they can talk to the guys round about them and bring them on. Joey will not hold back."
He is Rangers fourth signing of the summer, with Jordan Rossiter also following duo Matt Crooks and Josh Windass - who signed pre-contract agreements earlier in the year - to Ibrox.
