Martyn Waghorn looks set to leave Rangers in January following showdown talks with Mark Warburton, according to a report.

The Scottish Sun claim that the striker, who scored 28 goals last season, is unhappy he has not been offered an improved contract like some of his teammates.

It is said that Waghorn met with manager Warburton at Murray Park on Wednesday and informed him of his desire to quit when the window re-opens.

Championship clubs Bristol City and Fulham interested in snapping up the 26-year-old in the new year.

The Scottish Sun report that Waghorn could even go on loan until the end of the season, but it seems certain he will move on one way or another.

The ex-Wigan man has watched Rob Kiernan, Wes Foderingham and James Tavernier get improved deals in recent months.

Waghorn wanted a bigger wage increase to put him on a par with big hitters Niko Kranjcar and Joe Garner.

The striker moved to Ibrox in the summer of 2015 and had an excellent debut campaign as he spearheaded Rangers’ Championship triumph and return to the top flight.

He has been far less effective this season, scoring just once in nine league matches, although five League Cup games have yielded seven goals.

In other Rangers transfer news, the club have lined up a 21-year-old to replace Joey Barton.
