In my opinion, Nottingham Forest will have a hard time against Manchester City because Manchester City will focus on the Premier League after being eliminated from the Champions League. Although Nottingham seems to be performing well, I think they will lose in the Manchester match this year. If Nottingham Forest gets 3 points, this will become a problem for Manchester City.
For Pep Guardiola they have lost their way in the Champions League with their early elimination this season. Of course their next focus will be on the Premier League to occupy third place, especially since the points difference is not too much with Nottingham Forest so it will be easy for Manchester City to take third place. Even if Arsenal is inconsistent, Manchester City could also overtake them because the season still has many matches left.
Nottingham Forest previously ran quite well in the first half of the season but they lost control in several matches which made their performance unstable, this opened up opportunities for Manchester City to overtake them. For me, Nottingham Forest will have difficulty closing the season in the top 4 because Chelsea also has a great chance of doing anything to be able to penetrate the top four.
