5 talking points as Rangers have Champions League mountain to climb after Union Saint Gilloise humbling

Rangers slipped in their bid to reach the Champions League group stage as Union Saint Gilloise secured a historic and deserved win in the first leg of the third round qualifier.

Gio Van Bronckhorst is aiming to lead the Ibrox side into the group stage of UEFA's premier tournament for the first time in 12 years but faces an uphill battle in the return leg. The Europa League finalists came into the clash at the Den Dreef Stadium as heavy favourites but Teddy Teuma netted the Belgian's first goal in European competition in 58 years before Dante Vanzeir's penalty gave USG a comfortable lead.

Rangers got off to a bright against the resolute home defence with Borna Barisic's curled free-kick from the edge of the box forcing USG goalkeeper Anthony Moris to stick out a strong hand to deny him. James Sands was next to try his luck with a powerful long-range effort, but the well-struck drive was smothered by Moris to deny the American his first goal for the club.

These would prove to be Rangers only efforts on target throughout the 90 during a toothless display, as the hosts went through the gears. And they could have had the advantage in the tie as John Lundstram was caught in possession by Loic Lapoussin.

He raced down the left flank to whip a dangerous ball to the feet of Vanzeir. Sands sensed the danger and stuck out a toe in the six-yard box to deny the frontman a clear contact, and he fired wide.

That should have acted as a warning call but moments later the Belgians took the lead. Passive defending from Borna Barisic allowed Amani to play a neat pass to Teuma. The skipper made no mistake as he lashed the ball into the net and through Jon McLaughlin.

Into the second half, Rangers struggled to dictate the pace of the game
