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.
