Focusing on one of them might actually be quite good. But I think Jurgen Klopp can divide his focus between the two, namely the Premier League and the European League. Because Man City can also do it, Liverpool can definitely do it too. Even Man City is also dividing its focus with more competitions such as the FA Cup, UCL and Premier League. So Klopp's task actually didn't become more complicated after Liverpool were eliminated from the FA Cup. He just has to try to stay consistent in the Premier League and then he also has to keep going further in the Europa League. The match schedules are not that close together. So I think the squad that Liverpool currently has is enough to be able to perform optimally in both competitions. It's just that I agree that Leverkusen is the real challenge in the Europa League. Liverpool must hope not to meet Leverkusen early.
Klopp should focus on one competition, which is the only thing that I think might help him this season. You know, the Premier League competition is not like the Europa League; the Premier League is tougher than the Europa League, so given that the clubs that are fighting for the title here are very good squads with a high chance of getting it, I think it will be better if Liverpool focus on the Europa, and you know that the squads in the Europa are tough like the ones in the Premier League, so I think it will favor them if they focus on one.
and this will even give them more chances of getting the one they focus on because even if the players won't be much stressed out because I believe playing and dominating in all the matches that they must win, both tittle may even result in losing it both because the players may even start getting injured and currently some of their players are not even around, so you will see that there will be problems if they put focus on both.
I understand the logic, but not like Europa has many more games left, it's like what 5 more games? Quarter finals will be 2, semi finals will be 2, and finals will be a single game. So, "focusing" on premier league doesn't mean that you should ignore these five games. If it was many many games, then I would agree, but when it is only five games left I think it's not that important anymore. We should consider them as doing something that will not be causing too much trouble.
It should definitely be something that will take a while to guess, and I believe that it could reach to a point where it's going to end up with a greater return. Just win both of them, it's not that hard, they just have to keep winning like they are doing right now.
