It was a huge win for Liverpool and I feel sorry for Arsenal for their early exit from the tournament. Arsenal are lacking a good stricker and they need to get that settle immediately if they are to change their fortune anytime soon.
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. Arsenal more dominated the match, they created more chances in scoring goals. But Arsenal fails to score a single goal, we can assume Arsenal players has lack of accuracy in shooting. If they have good accuracy, Arsenal may score many goal during the match.
