It makes sense, because next season the competition for the top four in the Premier League will certainly be a difficult job. So yes, because Liverpool are playing in the Europa League, at least Liverpool will have the access that maybe they can definitely get by winning the Europa League title to be able to get Champions League tickets. But yeah, that doesn't mean Liverpool will relax in the Premier League because anyway, I'm sure Liverpool will keep working hard to be able to finish in the top four too later. Of course this will be a very interesting competition, I don't think Liverpool will fail to get a Champions League ticket later.
Indeed, Liverpool's focus will remain on two competitions and of course it will not be easy because there will be a lot of pressure that arises due to increasingly competitive competition between teams. Maybe if Liverpool can win the European league then they don't need to bother looking for a place in the top 4, but one thing is certain they will keep trying to return to the competition at the top of the standings. After all, there is nothing wrong if Liverpool are serious this time in the European league and if they can win the European league title then at least they have one trophy next season.
I agree somehow partially because still I believe their main focus is Premier League because we all know how unpredictable are UEFA competitions so going into Champions League through Europa Cup is much risky for them with this most chances they will again try their best for the best in Premier League because in last season they were not good but still they achieve good results in last few weeks from here they can do much better and conveniently.
With in Europa Cup things are also manageable until we have round of 16 after this it's never been easy for any team to stay at same level like we have few teams in last season like Arsenal, Manchester United and Juventus but still we can expect good fight for this title from Liverpool and Jürgen Klopp.
