That's true, they will now concentrate on premier league since there is no any other title they're competing apart from premier league. So I think liverpool will be very consistent this time, since psg have relieved them from going through the champions league stress. Though is so funny to say this, but that's the fact. However, I think there is nothing for them to worry about because the point distance is very huge of which you and I know that the possibility for any team to come from behind and win the title is 0% because I can't even imagine this happening.
Yeah even though we were all shocked by Liverpool defeat in the Champions League but on the other hand this will be the right moment to focus on the local league, as we know Liverpool is 90% on the right track for the title so they just need to wait for this season to end. Arsenal may be Liverpool's closest rivals but currently Arsenal are still competing in the Champions League so this will affect their performance in the Premier League that's why I say arsenal has no way to catch up with liverpool.
Liverpool lost in the UCL from PSG which knocked them out not only surprised everyone but also very undeserved because Liverpool itself was previously the strongest team that topped the standings, and one thing to note is that Liverpool elimination from the UCL competition will not affect anything even as long as they have not been eliminated it will remain the same.
Difference between Liverpool and Arsenal who are in second place is now 15 points, this clearly shows that Liverpool in winning the Premier League title is very guaranteed and they also only have 9 match left which even if they suffer 2 or 3 lost will not change their position from the top of the standings.
