It is no longer possible for other clubs to take over Liverpool's position in the first ranking if we look at it logically. (unless something very big happens and it is beyond our control).
After being eliminated from the UCL, now they can focus 100% on the EPL to keep their position safe until the end of the season. They just missed out on a huge opportunity as they were robbed by PSG at Anfield, but the chance to win the EPL trophy should not be wasted because it would be something to be proud of for their hard work this season.
15 points gap
10 matches remaining
Correction.
Liverpool have played 29 games, meaning they still have 9 left.
They just need to win 6 out of the remaining 9 games this season to win the title race, I don't think that's something that's difficult because they are still very consistent in the EPL.
