Rangers will face Monaco or PSV Eindhoven if they are able to beat Union Saint-Gilloise to make it into the Champions League play-offs.
The Europa League runners-up begin their Champions League qualification campaign today with a trip to Belgium to take on Union Saint-Gilloise, who finished second in the Belgian First Division A last season.
The return leg takes place at Ibrox on Tuesday, August 9.
If Rangers beat Union Saint-Gilloise to reach the play-off round they will come up against either France’s Monaco or PSV of the Netherlands.
Rangers are due to be at home in the first leg on August 16-17 if they reach the play-offs.
The Scottish Premiership side reached the final of the Europa League last season, where they lost on penalty kicks to Eintracht Frankfurt.
