Rangers left themselves with work to do to see off Servette after a narrow 2-1 win over the Swiss side in the first leg of their Champions League third qualifying round at Ibrox.
Skipper James Tavernier scored a penalty in the sixth minute before striker Cyriel Dessers knocked in a second eight minutes later for his first Gers goal.
The Light Blues were in command but, just before the break, Servette attacker Chris Bedia reduced the deficit from the spot after the VAR intervened to flag up a Dessers handball.
Servette’s hapless David Douline, who conceded the penalty for a foul on Todd Cantwell, was sent off in the 59th minute for picking up the second of two yellow cards for a foul on the Light Blues midfielder to leave his side with 10 men for more than half an hour.
However, the resolute visitors prevented further damage and will fancy their chances of turning the tie around in Switzerland next Tuesday night.
