The referees have been assigned for Champions League key games Celtic-Milan and Borussia Dortmund-Napoli.
Both kick off at 19.45 GMT on Tuesday evening and will be crucial results for qualification.
Milan visit Glasgow with Turkish referee Cuneyt Cakir wielding the whistle.
It is his second game of the season with the Rossoneri, as he officiated the 1-1 play-off draw away to PSV Eindhoven.
Napoli go head-to-head with Borussia in Dortmund and their referee is Spaniard Carlos Velasco Carballo.
He brings back fond memories for the Partenopei, officiating their 3-1 victory over Chelsea in February 2012.
