For me both team have equal chance of winning this match. Maybe Nottingham Forest would have a slight advantage since they are playing at home in City Ground. My assumption is based on both team's last three games. Both of them have won two and drew one making them equals in my perspective.
I have so much respect for Nuno Espírito Santo because he has proved to be a good maximizer of resources. He was able to use some relatively average to compete for the top three in the EPL. Ruben Amorim is still struggling to find his bearing in the league, maybe he would show some class in this important game.
If you judge the two teams by their performance, Nottingham Forest should carry the day because obviously they're the better side. But again, Manchester United had some good results under Amorim before the break. So It might be that he's beginning to put the pieces together or it's just a mirage. The game tonight will tell us more about this but I'm hoping they don't disappoint me because my money is on the line.
