An early strike from Saul Niguez was all that separated Atletico Madrid and Liverpool as the Spanish side will take a 1-0 lead into the second leg of their Champions League. Liverpool were caught cold from a corner early on and Saul was on hand to poke home. What followed was a typical Atletico performance under Diego Simeone, albeit not something their fans will have seen too often. The second leg will take place at Anfield in just over three weeks time. Elsewhere, Borussia Dortmund teenager Erling Haaland scored twice in eight minutes to lead his team to a 2-1 victory over Paris St Germain.  The Norwegian 19-year-old, who has already netted eight times in five Bundesliga matches, stabbed in from close range after a quickfire passing move in the 69th minute and then thundered in an unstoppable shot for his second in the 77th, two minutes after Neymar had levelled for the French champions. Haaland has now scored 10 Champions League goals in seven games this season -- eight for Salzburg in the group stage. The return leg is in Paris on March 11. Re-Live the action:
