Danny Mills has stated that Joey Barton is “very, very difficult to understand”, as he slammed the Rangers midfielder for thinking he is a good footballer.

Sky Sports News reporter Kaveh Solhekol reported on his personal Twitter account on Wednesday afternoon that Barton will be training with the club’s academy players.

The 34-year-old was banished from first-team football, after a training ground incident involving teammate Andy Halliday, following the 5-1 defeat to Celtic in September.

He arrived at the Gers Auchenhowie training base on Thursday morning, returning from a recently imposed club suspension.

Former England international Danny Mills, who played with Barton at Manchester City, had this to say about the controversial player following his return to training.

“Complex to the nth degree [on what Barton is like],” Mills told BBC Radio Scotland ” Joey’s very, very difficult to understand at times. I got changed next to him every day for four, four-and-a-half years, whatever it was at Manchester City; was there every time things went wrong.

“He’s a very, very good footballer. I’ve said before I don’t think he’s as good as he thinks he is and he expects everybody else to be as good as he thinks he is. That’s one of his problems.

“Occasionally, a switch goes and he just goes off track and he has no empathy, no remorse for his actions.

“From being on the outside, it seems quite clear that Rangers are trying to freeze him out, trying to upset him. I’ve been in a similar situation before, I’ve seen it happen. I think it’s going to be very, very difficult for him.”

Barton has appeared eight times for the Glasgow giants in all competitions, following his free-transfer in the summer.

He helped Sean Dyche’s Burnley earn promotion last season, but decided against renewing his contract with the Premier League club.
