Some tinkering to Rangers' system had been long overdue, with the side having not kept a clean sheet in five weeks and falling two behind in their previous two outings.
The switch to three at the back offered some advantages defensively but the formation's principle aim was to carry a threat on the counter, as exemplified by the Vaclav Cerny double.
While Rangers may have belied their status as underdogs, the result and display are not entirely surprising, given their wins in Malmo and Nice earlier in the competition and solid home victories against FCSB and Union Saint-Gilloise.
There's still work to be done to reach the Europa League last eight but, with no domestic fixture this weekend, Barry Ferguson and his players have a week to prepare for the second leg and the chance to set up a quarter-final meeting with Roma or Athletic Bilbao.

Jose Mourinho was, as ever, good value in the run-up to this game and will likely hold a captive audience when his Fenerbahce side travel to Glasgow next week.
He certainly has the nous - and the players - to turn the tie around at Ibrox.
Captain Eden Dzeko looked particularly dangerous, while second-half sub Allan Saint-Maximin's dangerous delivery was nodded just wide by En-Nesyri, who was later foiled by Jack Butland. Anderson Talisca also tested the keeper.
And with Fred free from suspension to bolster Mourinho's options next week, the decider is all set up for a fascinating contest.
