Arsenal deserves to win without a doubt! They are having an outstanding season so far and today's game against United should bring them another victory even if United are having a great run lately that will make them to fight for points.
I'm support Manchester United to win this match even though Arsenal are the favourites. It's hard to expect this fight to go according to plan because both teams actually need points. A draw isn't completely disappointing, but of course winning is the main target.
Arsenal won 7 of their 8 home matches this season, while 1 other match ended draw. It may not be problem to expect Arsenal to win, but Manchester United are coming to take 3 points from Arsenal. I'm sure about that, and basically, no matter how small the chance for Manchester United to win is still chance.
I can also agree with you that this game can end up with a draw, and , I'm sure neither of them will be upset by just taking 1 point from the game. However, we are still some hours away and maybe first eleven for both of them can change meanwhile.
Actually I'm not really expecting a draw, but the 3 points at Arsenal will be very important.
Meanwhile, Manchester City won the first half against Wolves, and Haaland has scored who will likely get a few more goals in the second half.
