Waghorn has been in superb form for Rangers since joining the Gers from English League One club Wigan Athletic in the summer transfer window.
The striker has scored as many as 11 goals in the Scottish Championship this campaign and has been hugely important to Rangers’ challenge for the league title.
Clark seems to think highly of 25-year-old Waghorn, and believes that he is more than just a goalscorer.
"Waggy has been great, but not just in terms of his goals, but his overall performances too."— Rangers FC (@RangersFC) October 1, 2015
Rangers are on course for promotion to the Scottish Premiership and have been in brilliant form so far this season.
Mark Warburton’s side are at the top of the league table at the moment with 24 points from eight matches, nine points clear of second-place Falkirk, who have a game in hand.
Rangers will take on Falkirk at Ibrox in Glasgow in the Scottish Championship on Saturday.
