Turkish referee Cuneyt Cakir will be in charge of Real Madrid's last 16 Champions League tie against Manchester United.
Los Blancos travel to Old Trafford on Tuesday for the second-leg of their European clash, with the game finely balanced at 1-1.
The 36-year-old has already refereed Jose Mourinho's side once before this term – the 2-2 draw with Borussia Dortmund at Santiago Bernabeu.
Cakir has been an elite official since 2010 and was in charge for Barcelona's Champions League elimination to Chelsea last year, as well as the Euro 2012 semi-final between Spain and Portugal.
