I also think so, especially from what Nottingham Forest has achieved so far, of course, it has drastically increased the mentality and confidence of the Nottingham Forest team, now Nottingham Forest is very close to finishing in the top 4 so I think they will give everything in the remaining matches this season to achieve that.
The match against Man United will not be easy and it is not meant to underestimate Manchester United, but let's just look realistically that Nottingham Forest's strength is slightly better and on the other hand Manchester United has not proven the consistency of their performance so far even though in the last few matches they have played well, but I think they will not be able to repeat it in the match this weekend at Nottingham Forest's home.
Nottingham Forest was even able to beat Man City and Liverpool this season. So I think hoping that Nottingham Forest will produce the same result in the match against Man United is quite realistic given Man United's current condition. Because Nottingham this season has had a series of match results that are much better than other teams apart from Arsenal and Liverpool. Meanwhile, we know that Man United is in a slump, even though they are also trying to get up. But I think their strength may still not be enough to beat Nottingham. I also have doubts about who will win that match. But talking about the data available this season, Nottingham is indeed the most likely to win this match. Nottingham is currently in third place not just because of luck but because they work hard and deserve it.
With all sense of modesty I believe Nottingham Forest will replicate the same feat they had against Manchester city and Liverpool when they face Manchester United. Nottingham forest has proven beyond every reasonable doubt that they are capable of facing any of the top five teams in the Premier League, Manchester United isn't in a perfect condition at the moment so I don't think they would be much of a problem for Nottingham Forest to handle.
Though its going to be a tough game for both teams because the 3 points involved is of great essence for team, the Manchester side need all the points to move up the table whereas Nottingham forest need the points to continue in their quest for European football next season and that's why this fixture is quite important for both sides.
