Amad Diallo had the perfect start to his Rangers career as he scored just five minutes into his debut.
Rangers face tenth-place Ross County on Saturday ahead of their crunch clash with Celtic on Wednesday and Giovanni van Bronckhorst's side immediately had the upper hand as Diallo put them ahead early on.
The 19-year-old signed for the Scottish Premier League champions on a six-month loan deal from Manchester United on Thursday.
Rangers boss Van Bronckhorst made the shock decision to immediately start the winger on the right flank for Saturday's game.
