Arsenal are once again not strong enough to chase the leader, and Liverpool are just lucky that City are at a turning point this season when they need to update their squad, when there is the loss of such an important player as Rodri and frequent injuries to other players, especially at the beginning of the season, all this played into the hands of Liverpool, and they are moving towards the title without feeling any competition from their rivals, and Arsenal will again be second.
Manchester City from 2016 to 2020, that's 4 years and they won the Premier League only once. It was after the careful selection of these squad that the team formation changes and improves the way they were playing and now that the strategy is not working you think Liverpool is lucky? No, this is not luck, this is their own strategy of play and it will continue like that until it no longer works for them, they have won the Premier League before now, this is not luck but their hard work.
Liverpool are winning this one and if the team remains the way they are, they will win the next one unless if we see comeback from other teams especially Manchester City. If they don't win anything this season and next, then I'm sure that we might witness another fun of Manchester City the way Chelsea had 3 season without anything and how Manchester United is struggling so hard to be relevant but nothing seems to be working in everything they are doing right now.
