#1 Lack of potency in front of goal cost Reds
At the end of regular time, that 1-1 scoreline will have left Jurgen Klopp disappointed, to say the least, as the Reds had so many opportunities to win the game but lacked the telling touch in from of goal.
In the first half, Mohamed Salah had two brilliant opportunities to send Liverpool in front but he didn't and in the second half as well, that same man missed many opportunities.
The one in injury time would have hurt him the most as he just had to beat Claudio Bravo from close range but the Spaniard came on top just as he did in the penalty shoot-out.
Although one can say Bravo made some great saves, but considering the quality of Salah, he should have buried at least one of those opportunities. At the end of the day, it was that lack of potency in front of goal that finally lost Liverpool the game.
