The Turkish referee, Cunet Cakir, will referee the Juventus-Real Madrid Champions League fixture on Tuesday, April 3, while Italian referee Daniele Orsato will do the same at Sevilla-Bayern.
Both are first-leg matches in the quarterfinals of the competition.
Cakir is a veteran at the top level and has been since 2007, and he is also one of the whistle blowers appointed to the World Cup.
On eight previous occasions, Cakir has taken charge of a game involving Real Madrid, with a balance of four Los Blancos wins, two draws and two defeats.
Juventus have won one and lost one with the Turk in the middle.
Orsato is 43 years old and a member of the elite category since 2012.
He has taken charge of Sevilla twice before; on March 14, 2017, in a 2-0 loss to Leicester, and on March 12, 2015, when the Andalusians triumphed 3-1 over Villarreal in the last 32 of the Europa League.
