Warburton's first season with Glasgow Rangers was sensational, but life has proved slightly tougher in his second campaign at Ibrox.
Rangers manager Mark Warburton
Gordon Durie has explained to The Scottish Sun that his one concern about current Rangers boss Mark Warburton centres around his willingness to include the youngsters coming through at Ibrox in his first-team.
Warburton has enjoyed a promising time with the Gers. After delivering promotion and a victory in an Old Firm game last season, life has been slightly tougher for the club this term.
Though they sit third in the Scottish Premiership table, they are well adrift of the league leaders and have played a game more than Celtic.
However, former under-20s coach Durie appears to be relatively content with the job that Warburton has done, but did express what has disappointed him slightly.

He told The Scottish Sun: "Andy Murdoch, Tom Walsh and Ryan Hardie all had a little taste of it but do the young kids get a chance?
"That's my only doubt about Warburton.
"He farms out the young guys and brings in young players from England instead."
Warburton has overseen the arrival of 27 players since he was appointed by the Light Blues. And with many of those players proving to be important first-team members, it is not difficult to see why Durie has concerns.
Rangers have several exciting youngsters that are trying to make the grade at Murray Park, but it is fair to say that they currently have their path to the first-team blocked by several more experienced players.
But Warburton may argue that the club is still going through a transitional phase as they try and adapt to life at the highest level. And once that transition is complete, then they can perhaps begin to start handing the brightest prospects more opportunities.
