Union Saint-Gilloise will head into the return Champions League showdown with Rangers on the back of a thumping in their domestic league.
The Belgian outfit inflicted a two-nil defeat on Giovanni van Bronckhorst's men during the week in the first meeting of their third qualifying round clash. However, while the Light Blues ran out 2-0 winners over Kilmarnock to maintain their 100 per cent start to the new Premiership season, their Euro rivals were hammered 3-0 on the road at K.V. Mechelen.
The home side had lost their opening two games of the campaign while Union had picked up four points from the first two games - but it was the out of form side who came out on top against Karel Geraerts side to move away from the foot of the table, and deliver a major confidence blow ahead of the trip to Ibrox on Tuesday night. Rob Schoofs grabbed the opener for the hosts in the first period before a quick-fire second-half double via an own goal from Jean Thierry Lazare Amani and Julien Ngoy secured the points.
