Newcastle's current Goal Difference has also surpassed other teams like Manchester City so I think Newcastle can stay in the top three until the end of this season and could even be the runner-up team in the Premier League this season if Arsenal are not consistent in winning the rest of this season. Because at the moment Newcastle are really focused on the Premier League so the increase in position that Newcastle has achieved is really very real and very extraordinary for the rest of this season.
Rank 1- 4 is good enough and I am more curious about which teams will be able to compete for the top 5 positions to qualify for the UCL. Even though actually occupying the runner up position or 3rd, 4th and 5th will not be a problem because all of them will still be in the UCL. This additional slot is a good opportunity for teams like Manchester City, Chelsea, and Aston Villa to maximize their chances. With the gap still very thin, these 3 teams will continue to elbow each other and we will see at the end of the season because there will be 1 team that will be eliminated.
