Controversial German referee Felix Brych has been named as the man to take charge of Milan-Barcelona on Tuesday.
The Rossoneri host the Blaugrana in their third Champions League group stage match next week.
And UEFA have confirmed that it will be the 38-year-old who will be the official for the match at San Siro.
Brych has come in for some criticism recently after he allowed a goal in the Bayer Leverkusen-Hoffenheim game that went in through a hole in the side-netting.
The Munich-born referee has taken charge of Barcelona before, having overseen the 2012 semi-final first leg with Chelsea.
