English referee Anthony Taylor will be at the whistle when Roma are looking for a place in the semi-finals of the Europa League.
The Giallorossi picked up a 2-1 win in Amstserdam last week and the tie will be decided on Thursday, when the Dutch giants arrive at the Olimicpo for a 20.00 UK time kick-off.
The UEFA has announced Taylor will be in charge of the game, and will have assistants Gary Beswick and Adam Nunn by his side.
The fourth official is David Coote, whilst Stuart Attwell will be in the VAR room with assistant Paul Tierney.
