Honestly, I think it is easier for Liverpool to win the Premier League trophy this season, in fact I think Liverpool should be given the trophy already. There is no team stopping them now in the Premier League but the Champions League is a whole other competition. Liverpool are in good form but they are not the best in terms of squad depth when compared to the other teams like Real Madrid, PSG. I don’t see Liverpool as favorites to lift the Champions League trophy this season.
In football, before a final whistle of a match or completion of a season final match day, there is no guarantee on a winner of a match or champion of the league. Liverpool have good advantage now in point difference with Arsenal and they have excellent form too, but they have to focus and fight till the season ending. 11 points are only temporary difference and it can become only 8 points if Arsenal win their match. With 8 points, three bad matches can change many things but I agree that with only 11 matches left, Liverpool will hardly lose 3 matches and lose their good advantage in the title race this way.
Arsenal will very likely have to wait one more season to win Premier League title, and perhaps this season will be a third consecutive season they finish Premier League season with a second position.
