That's the same for me because in the current conditions taking some bets on Arsenal is a bit of a risk so it's better to hold off.
For other games like Manchester United it's the same because the performance of this team when facing a much more balanced team is difficult to predict and there is probably a lot more potential for a draw.
For the current position I won't bet because it's difficult to make predictions because both teams playing will try to do their best so it's difficult to predict.
Nottingham are favourites in this match, but it is difficult to bet against Manchester United, I agree with that, even when we see that they are not doing very well. And sometimes they do have good matches, but I doubt that they can count on anything more than a draw now, and that is in the best case. And you are right that it is better to leave this match and not think about betting on it, although I have thoughts that Nottingham will be able to score and not lose this match.
Without been bias Nothingham forest has more form than Manchester united and so judging with that it is possible to say that Nothingham forest will win Manchester united but football doesn't work like that and secondly Manchester united is a very big team in England and in the whole world so that name and glory always come through for them and sometimes they always surprised people even when people have lost hope in them, it is going to be a tough match and if Manchester united can win Nothingham forest then it something great will happen.
