It's easy to guess who will win, of course it will be Manchester United. Manchester United's good form so far will see them as the favorites today. If Manchester United wins, then it will be their 8th win in a row after the World Cup break. I don't even think Crystal Palace will make things difficult for Rashford and co, and I think this will be a proving ground for Manchester United.
I can expect 2-3 goals for Manchester United to win, that's because they are absolutely great at the moment.
At the moment, bookmakers estimate the probability of United winning as 1.69. That is, United is the obvious favorite, but there is also a chance of losing points - about 40% according to the bookmakers (defeat or draw). You could say that this is an underestimation of United, but still United is not in the status to be expected from them for a long unmistakable winning streak.
