For this Premier League season, you can already consider Liverpool as the champion and you can consider Arsenal as the second position, but there will be a competition between several teams in the Premier League for the third and fourth positions in the points table.
You also need to know the bottom 3 teams that are likely to be relegated are working hard to stay in the EPL. They are Ipswich, Leicester, and Southampton. The two teams Ipswich and Southampton do not have much point difference with 16th place only 5 points. So there is a chance to stay. The difficult thing is that Southampton they only have 9 points from 27 matches.
Meanwhile for the Championship Leeds, Sheffield and Burnley are strong candidates for promotion. Even though we still have 7 games left, I think these 3 teams are the best candidates to replace the bottom 3 of the EPL rankings.
So far we have only focused on the top competition between the big teams fighting for the championship trophy, so that we no see the intense competition that also occurs at the bottom between the teams that are trying to get out of the relegation zone this season, southampton, which currently has only 9 points and a difference of 13 points from the team in the safe zone, is a strong candidate for relegation, while ipswich and leicester city, they actually.still have a chance to stay in the premier league next season, especially if they can maximise the remaining 11 games by winning points, although it is difficult of course they must be motivated to be able to do it especially when leicester city actually has a pretty good quality squad and experience, about the promotion team next season it seems what you said is quite realistic about the chances of leeds and Sheffield escaping, but it seems burnley will have to face a big challenge and in my opinion, sunderland will be their challenge to get back promotion to the premier league next season.
