Champions League: New format negates Atletico Madrid's experience, says RB Leipzig's Julian Nagelsmann
RB Leipzig, founded in 2009, are in the Champions League's knock-out stages for the first time in the club's brief history. In contrast, their opponents Atletico Madrid reached the 2014 and 2016 Champions League finals.
The new format could suit Atletico Madrid, in single matches where game management is likely to be key and technical superiority has less time to win out than over the traditional 180 minutes.
Real Madrid are the only team with a perfect record since the restart. They have had seven straight win since the league resumed, leaving them four points ahead of second-place Barcelona with four matches left.
In March when the league was halted, Atlético were struggling to secure a Champions League berth for next season. They are now well on course to finishing third.
