Liverpool was actually doing well in the Champions League untill they were unlucky on the day it mattered the most so it wasn't like they haven't been doing well at the champions league, literally they were at the top of the table at the league stage and so they were even perceived to turn out a very strong contender at that point but then they got unlucky and crashed out but now the premier league is the only hope for a trophy this season. Arsenal has gat almost no chance at the Premier league but they do at the champions league so they can go ahead to put in the effort and possibly get an opportunity to likely get the champions title hopefully even with the strong opposition they will be actually facing.
There is nothing like Liverpool being unlucky. They got Outclassed by PSG. Simple as that. If you are a person who watched both legs and understands football. You would agree with me on this.
I don't know why most people take about luck in football. it's as though the other team never put any effort at all. It's total disrespect. Well, sorry to break it to you, goals won't score themselves, will they?
