The first leg of the 2014/15 UEFA Champions League quarter-finals took place on Tuesday night.
In Turin, Juventus got the better of Monaco 1-0 to give themselves a slight advantage going into the return bout next week.
The Juventus Stadium clash featured a number of chances, especially for the Bianconeri, who are now on the verge of reaching the semi-finals for the first time since 2003.
Juventus hit the front in the 57th minute when Arturo Vidal stepped up to the spot after Ricardo Carvalho had brought down Alvaro Morata in the area while attempting to clear an aerial ball.
Chile international Vidal finished emphatically from 12 yards, smashing his spot-kick into the top left corner, with Danijel Subasic selecting the wrong way.
The Serie A champions will now prepare to head to the Stade Louis II next Wednesday for the second leg.
In Spain, Real Madrid managed to produce a positive result at Atletico Madrid for the first time in four outings as they drew 0-0 at the Vicente Calderon.
Los Blancos had lost their past three meetings at the venue but Carlo Ancelotti's men this time created the better of the chances with Atleti keeper Jan Oblak the savior after pulling off a number of quality saves.
The visitors were unlucky not to score, however, Diego Simeone's los Rojiblancos produced some chances late to set up what promises to be a classic encounter at the Santiago Bernabeu next week.
Wednesday night's fixtures sees Paris Saint-Germain host Barcelona at Parc des Princes while Bayern Munich take on FC Porto in Portugal.
