After a flurry of chances for the home side, Suárez leveled from close range in the 63rd minute and then headed the winner in the 74th, giving the European champions the edge before next week's second leg at the Vicente Calderon.Atlético got off to the ideal start when Torres fired Koke's pass through the legs of keeper Marc-Andre ter Stegen after 25 minutes but 10 minutes later he was dismissed for a second booking as they suffered a seventh straight loss to Barca.Atlético had been in confident mood after thrashing Real Betis 5-1 in la Liga on Saturday and were looking to take advantage of Barcelona

.The former Liverpool and Chelsea striker received his first booking for a late tackle on Neymar in the middle of the pitch four minutes after scoring and got his marching orders for a second yellow minutes later for fouling Sergio Busquets.[caption id="attachment_11164" align="alignleft" width="300"]

broke Atletico's resistance when Suárez diverted Jordi Alba's low cross home with his shin and then powered into the area to head Dani Alves' cross past Jan Oblak to score the winner with his eighth Champions League goal this season.
