Mystery surrounds the future of Mark Warburton with contract talks at Rangers not progressing, according to a report.

The Ibrox manager has two years to run on his current deal and talks over new terms were put on hold following the Scottish Cup Final in May.

He then went on holiday before spending a week doing coaching badges at St George’s Park.

The Guardian claims that Warburton believes there is no way he will be leaving at this stage but talks have reached a stalemate and his future remains up in the air.

Football Insider last week reported that talks would resume this week after the Glasgow giants have returned from a pre-season trip to the US.

“We had open discussions, then I went on holiday, Warburton said last week, as quoted by the Scottish Sun. “We will re-open these discussion when we go back and hopefully reach a suitable conclusion.

The former Brentford manager is contracted with Rangers until June 2018 but looks set to extend his time at Ibrox.

Warburton helped his side clinch the Scottish Championship title last season and sealed the return of Rangers to the Premiership after a four year absence.

His only previous experience in management came during his two-year spell with Brentford, who he got promoted from League One as runners up.

Preparations have already begun and the manager has been quick to bolster his squad for the upcoming season, with the likes of Joey Barton, Niko Kranjcar and Jordan Rossiter signing.

With these additions Warburton will be hoping they can challenge Old Firm rivals Celtic for the title next season.
