Atletico winning 1-0 by scoring early and dropping deep had crossed my mind before the game. That 442 low-block high intensity with the right applications can be very hard on Liverpool and Atletico might knock them out, but the 2nd leg is at Anfield, it will be more difficult for Atm than for Liverpool.
If Atletico could have won 2:0 or 3:0 then it'd be more diffcult for them yes cause in that case Liverpool would have nothing to lose and probably storms into attack from first min ...
Since it's not the case i'd imagine it's actually harder for Liverpool cause they know they cant storm into attack straight away + they may easily need to score 3 goals to make sure Atletico dont have any chance to knock them out (on awaygoals) ...
However yeah it's intresting to see which streak is going to end few weeks time
A. Atletico loses for the first time under Simeone CL knockout match to team which dont have Ronaldo ...
B. Liverpool loses first 2-leg european match under Klopp
