It is very difficult for Nottingham Forest to stay in the top four of the table at the moment. Newcastle can only occupy the third place in the table if they win their next match. City is 2 points behind Nottingham and Chelsea are 3 points behind them. So if Nottingham Forest loses a point in the next match, it is uncertain for them to stay in the top four of the table.
If Nottingham Forest qualifies for the Champions League, they may be eliminated in the first round. But for these medium and small teams, qualifying for the Champions League is a big achievement. After that, the Premier League will become more competitive day by day. Small teams like Newcastle and Nottingham Forest are gradually becoming stronger.
Newcastle is the new hot guy in the Premier League, they will win their next match to balance with the rest of the team to occupy the third place and Newcastle is going to be fighting their ass up to take back the third place again but as along as Nottingham Forest win their matches, they will be able to retain the third place until the end of the season and seeing how Nottingham are not consistent while Newcastle are new hot cake, there will like be there until the end.
Chelsea and Manchester City faith is in the hands of their performance. I don't know what to really predict between these two teams because they looks both like half baked team that don't know what they want. Today they are at the top and tomorrow they are at the bottom of the top 4, if Nottingham and Newcastle doesn't give them a place to rest, they will finish the season without going anywhere, either sette for Europa or conference.
