Liverpool have not performed well in the Champions League this season, making it a bit easier for Liverpool to perform consistently well in the Premier League. Although they are playing in the Europa League, the Europa League teams are relatively weak.
Yeah well that's also a reason but I think to play two competitions simultaneously no matter what the difficulty isn't an easy feat for any club.
Liverpool played very poorly last season. But their performance has been very stable since the beginning of this season. They have been able to maintain consistency. At the same time, Liverpool players are not getting too many major injuries. This is why their performance is stable. While Arsenal and Manchester City have dropped points in several matches, Liverpool have managed to hold on to the top spot in the points table.
Last season they had injuries and all and Klopp had hard time to choose his strong midfield. I am glad that now they are back on track and are moving things the way they earlier used to. There are certain players who are yet to perform at the top level so there is still some development needed. Yes, this season they hadn't had much injury issues so they are running out fine but they might want to use their players carefully otherwise they will go back to the same position they were in last season. Well not like same position but certainly will drop a few places back but it will hurt given how hard they have performed so far and to come out and lose in the end.
