Joey Barton has posted a tweet celebrating the International Day of Peace – 48 hours after being banned by Rangers following the latest bust-up in his controversial career.

The 34-year-old has been embroiled in speculation over his Rangers future this week after he was suspended for three weeks following a training ground spat with midfielder Andy Halliday.

However, the former Manchester City midfielder posted on his personal Twitter account to his 3.25 million followers the seemingly ironic message that they should “show good will to all human kind.”

The midfielder is also under investigation from the Scottish FA, after it was alleged that he had placed a bet on Barcelona to inflict a heavy defeat on Rangers’ Old Firm rivals Celtic. A decision will be made by the governing body when the gambling commission complete their probe.

Controversy has always surrounded the combative midfielder, with incidents like serving prison time for assault and the Premier League’s second biggest ban of 12 matches for his actions following a red card against Manchester City.

The midfielder moved to Glasgow in the summer in a surprise move after winning the Burnley player of the year award last season, and it had looked like the one-time England international had calmed down at the end of a fiery career.

However, his future at the club has now been cast in considerable doubt.
