The possibility of Chelsea being in the champions League next season depends on their performance in the remaining 8 matches left to play in the league, their win against Tottenham yesterday put them ahead of Manchester City with 1 point, I think they need to be consistent in the remaining games if they want to be in the champions League because Manchester City is one team that doesn't give up untill the end of the season so I think the right for who will be in the 4th play and the team to qualify for the champions League next season will be on till the last game in the league. Liverpool and Forest has already booked their tickets to the champions League competition next season I think Arsenal needs to be careful to avoid Forest finishing ahead of them because 4 points gap is not enough.
Chelsea must not only be wary of Manchester City because Newcastle is also in the same position, Newcastle could potentially overtake Chelsea from 4th place if they win their 30th match now we just have to wait and see who is the most consistent among these 3 teams to get the remaining ticket to the Champions League. Honestly, I'd rather see Chelsea take their place there especially they have been absent in this competition since the last few years and we know Chelsea have a good history here, I'm not talking about their potential as winners but as a more deserving team.
I don't see Newcastle as much threat to Chelsea as Manchester City if we want to consider the fact that Manchester City have been around the Champions League zone for a long time and would not want to lose it just yet. Newcastle on the other hand had the golden opportunity of even being higher in the league table this season but they have been so inconsistent, probably because they are comfortable with remaining in the Premiership even without a trophy or playing external competition. Therefore, Chelsea should be mindful of Manchester City who will fight with everything they've got to qualify for the UCL next season.
