Rangers have been paired with Spanish side Villarreal in the group stages of the Europa League.
The Scottish side are competing in the main stages of a European competition for the first time since the 2010-11 campaign after a 2-1 aggregate win over FC Ufa.
Rangers were placed in pot four, and it has resulted in tough fixtures against Villarreal and Russian giants Spartak Moscow.
Steven Gerrard's team will also go up against Rapid Vienna, who finished third in Austria last season.
The first matchday takes place on September 20.
