Joey Barton has yet to make his debut for Rangers or even have his first training session but the man is already getting himself acquainted with the club's most bitter rivals Celtic.
The controversial midfielder left Burnley to join the Glasgow club as they go about their first campaign in Scotland's top flight since entering administration in 2012.
He started his life north of the border by suggesting that Celtic's captain Scott Brown was "nowhere near his level" in terms of quality. Good start.

He told talkSPORT: "Of course, that’s the nature of being me. It comes with the territory.
"But without being disrespectful to the players up there, people keep talking about Joey Barton v Scott Brown. He’s not even in my league – he’s nowhere near the level of player I am."
Brown has since responded with his own quip, suggesting that he and Barton will probably get on famously, but only because he believes the Englishman is a Celtic fan himself.
"I've not been in his league, he's in my league," joked Scotland skipper Brown, 30.
"I think we'll get on really well, him being a Celtic fan, so I think we'll get on great."
Responding to the response
Well, you can not say something like that about Joey Barton and expect him to stay quiet. In fact, it took only minutes before the 33-year-old used the medium of Twitter to get his message across.
He tweeted: "Where I'm from you support one team. You might look for results of others foreign teams, but you only really support your team.
"If you were a dyed in the wool Everton supporter you don't wear Liverpool kits as a kid. In fact, you'd never be taken seriously if you did.
"I think what Scott meant was 'we'll both get on fine as we're both Rangers men!' It just seems Scott got a little confused. #WATP"
