Who is the referee?
Italy's Niccola Rizzoli will be in charge at the Aviva Stadium.
The 45-year-old refereed the 2014 World Cup final between Germany and Argentina at the Maracana, as well as the 2013 Champions League final between Bayern Munich and Borussia Dortmund at Wembley.
Won the award for Serie A's best referee five years in a row between 2011 and 2015 but will not be a popular figure with Manchester United fans.
Rizzoli sent off Rafael when they crashed out of the Champions League at the quarter-final stage in 2010, and failed to send off PSV's Hector Moreno for the challenge that left Luke Shaw with a broken leg in last season's competition.
