What do you think? by head to head in Fulham's home, Fulham never win and only one draw, the last 5 match Manchester United won it all.
That's why not surprising to see a bookie listing Manchester United is a favorite, because they already know this obvious stats.
Manchester United wasn't that bad when they met Arsenal, it just Arsenal was lucky enough the goal not ruled out.
I'm believing Manchester United will win.

The bookmakers would hardly consider a match from 2019 for their odds calculations. It depends on what the teams look like and whether they are still the same for the most part. It is now a new season and they give Manchester United the benefit of the doubt because they are supposed to come out on top in this match, but look how it ended at the end of last season. Manchester United 15th vs. Fulham 11th, 12 points ahead.
This game is definitely important for both teams. Whoever loses has a massively failed start and for Manchester United this would be worse than for Fulham. Both will feel the pressure.
