Joey Barton gives brutal assessment of Rangers after defeat to Celtic

By Dominic Toner

Joey Barton has posted on Twitter that there are “no excuses” for Rangers after the humiliating 5-1 defeat to Celtic on Saturday.

Mark Warburton’s side suffered a crushing loss to their Old Firm rivals in the Scottish Premiership which saw them slip four points behind Celtic, having also played a game more.

Barton, 34, and his Rangers team-mates were second best to Celtic all afternoon and youngster Moussa Dembele stole the headlines for his stunning hat-trick.

Barton took to his personal Twitter account on Sunday morning to reveal his embarrassment over the performance and claimed it was not good enough.

The club’s supporters took to Twitter to tear into Philippe Senderos after he endured a nightmare debut by being sent off in the second-half.

Rangers midfielder Barton, who was competing in his first Ibrox derby, could not use his wealth of experience to influence the match.

He has previously played at clubs such Manchester City, Marseille and Newcastle but is still adjusting to life in Scottish football.

Rangers cruised to the Scottish Championship title last season and are expected to challenge at the top-end of the table this year on the their return to the top-flight.

The defeat to Celtic will not define the outcome of their season but the Rangers players will have to start delivering to get the fans back on side.
