VAR to be employed in the Europa League knock stage
The Europa League round-of-32 begins on Thursday, featuring Arsenal, Celtic, Man Utd, Rangers and Wolves
Europa League will use the Video Assistant Referee (VAR) system in the upcoming knockout phase of the competition.
The first legs of the last 32 of the competition take place on Thursday February 20.
It was decided in September that VAR would be used after the group stages following a successful appearance in the Champions League.
Some of Europe's top referees have been taking part in a winter course in Mallorca to go through VAR analysis and training.
