Bundesliga side Leverkusen entered the match in fine form and made that count as it opened up a two-goal lead thanks to Kai Havertz and Charles Aranguiz.

Highly-rated midfielder Havertz opened the scoring from a penalty that was contentiously awarded by referee Szymon Marciniak and Aranguiz fired in a second after 67 minutes.

But Rangers pulled one back through George Edmundson and were pushing for an equaliser when dealt a sucker punch by Bailey's fine finish two minutes from time.
