For me, it is not a big win but it is surely an important win. Liverpool only scored 2 goals during the match, they also actually didn't dominate the match. However, they are lucky that they could score 2 goals in the match.
So you mean 2 goals to 0 is luck? I will like you to explain why it’s luck because Arsenal dominated the match, which makes them a better team. You have to know that nobody cares about the team that dominates a match, all everyone wants to see is the team that wins the match. Arsenal’s are now out of the FA Cup. Even if a club dominates a match and you can’t win, then the team that wins the match will be appreciated. Seriously, Liverpool played well by winning the match, and I will tell you, scoring two goals is no longer luck. Arsenal couldn’t secure any goals in the match, and you think it was lucky for Liverpool to win.
Arsenal's gameplay was good but they couldn't score any goals. On the other hand. the Liverpool team was tactical. They played defensively in the first half and Klopp tried to find the weaknesses in Arsenal's defence. And in the second half Liverpool were able to make some excellent attacks. This is why the result of the match was 2-0 till the end. Liverpool's defenders played very well. If the defense is not strong, it would be very difficult for Liverpool to resist a team like Arsenal. Salah and Szoboszlai were absent from the match due to injuries. If these two players were in the squad, maybe we would have seen a more organized gameplay from Liverpool.
