Los Blancos began the match brightly, spending most of the first ten minutes in the Juventus half before the visitors forced Thibaut Courtois into making the first save from a Weston McKennie attempt.
Madrid midfielder Aurelin Tchouameni then went close to scoring with two headers as the home team started to assert their dominance against the Italian side.
However, the Serie A side was able to absorb the pressure from the Spanish giants, who were constantly threatening on set pieces but failed to score as the teams went into the break goalless.
Juventus pressed for a goal in the opening minutes of the second half, with lively Turkish star Kenan Yildiz threatening Madrid's defence before Dusan Vlahovic broke free to test Courtois with a low shot in the 49th minute.

Madrid were unlucky not to extend their lead as Juventus goalkeeper Michele Di Gregorio pulled off a series of saves to keep his team in the match.
