Rodrigo de Paul was the match-winner for Atletico Madrid in their 2-1 victory at home to Cadiz on Friday night.
Diego Simeone's men came into the game on the back of three straight La Liga wins, and Joao Felix got them off to the perfect start by opening the scoring after just three minutes at the Wanda Metropolitano.
But after Alvaro Negredo levelled for the visitors on the stroke of half-time, De Paul then turned home the final goal of the game with 22 minutes remaining to ensure Atletico head to Manchester United for their Champions League last-16 second leg on Tuesday in strong form.
