Slovenian referee Slavko Vincic will referee Real Madrid-Milan. In contrast, England's Michael Oliver will referee PSV-Girona, matches scheduled for Tuesday's fourth round of the Champions League regular season, according to UEFA's website.

Vincic was the referee for Real Madrid's 2-0 win over Borussia Dortmund in the continental competition final.

The Slovenian referee was in charge of last season's Champions League match between Barcelona and Bayern Munich, which Bayern Munich won 4-1.

Vincic, 44, who has been an international since 2010, will be assisted on the sidelines by his compatriots Tomaz Klancnik and Andraz Kovacic, with Matej Jug as fourth official. Dutchman Pol van Boekel will be in charge of the VAR and Portugal's Tiago Martins will assist.

In the PSV-Girona (18.45), Oliver will be accompanied by English linemen Leet Betts and James Mainwaring and fourth official Andrew Madley, all English, and in the VAR, his compatriot David Coote and, as assistant, Scotland's Andrew Dallas.

Oliver, 39 and an international since 2012, has refereed Red Star-Benfica and Young Boys-Inter in the Champions League this season and last season refereed two Real Sociedad matches.

At this year's European Championship, he refereed four matches, including Spain-Croatia in the group stage and the quarter-final between Portugal and France.
