However, if Liverpool could keep this leader position up and get it, then Europa seems like easier target. They do not have many teams that could be considered their level, maybe one or two more teams at best and even that's arguable. That means, if they do end up losing, it will be a team that would be worse than them, and that's possible but it would be hard to do. I think Liverpool could win europa much easier than premier league.
It sounds odd at first to say that winning the Europa League is easier than winning the Premier League, but I think you nailed it since Manchester City is the opponent someone has to beat if the goal is to win the Premier League. The point average for Manchester City over all those last years is incredible, but on a positive note Liverpool has demonstrated a few times that they can play on the same level and get close to 100 points. But it needs a perfect season and anything less is not enough. In the Europa League they will always have one home game in every duel until the final. It's quite the difference.
