I consider Liverpool champions already because with 12 points gap and only nine games to play I don’t see a possibility of Liverpool slipping away not like Arsenal are going to win all their remaining matches even so for me the title race has ended already just give Liverpool the trophy. Can I call Arne Slot successful? Yes why not. He got to the league cup finals, got to Champions League knockout and if he achieved the league title ofcourse he has a successful season.
You are free to call Liverpool champions but it has not been official or certain yet because they are still 9 matches to play and anything can be possible. I doubt if there's any team that can try to challenge Liverpool again in the premier league because it almost over, the moment Arsenal loses 2-3 or draw and Liverpool wins then it will be official and Liverpool will be handed over the premier league trophy but for the main time it is not yet over untill it is over. And yes it has been a great season for Liverpool even though they fucked up in the EFL cup.
We can't really say anything shocking would happen though? Can we? Look at the league situation, plus Liverpool is out of everything else, so they only have the league games which means they are going to rest, Arsenal still has some games left outside of the league.
There is no way that a very well rested Liverpool would lose that many points whereas Arsenal would end up with all wins, so we can easily say that Liverpool will win the league. Sure it looks like we are not going to see that becoming a mathematical reality for a while longer, we need it to become mathematically possible first. However, just because math doesn't say it is done, doesn't make it any more competitive, we could see how the league is already done.
