Long injury list or not, Manchester United just do not have the players to go to Emirates Stadium and sit there and be hard to beat.
This looks like being an open game, which will suit Arsenal, and I do not know how United are going to cope with in-form Gunners striker Alexis Sanchez.
Arsenal have not had a great start to the season either, but I still see them as nailed on to finish in the top three this season and get a Champions League spot.
It is not the same for United, who I think will end up having to fight for fourth with the likes of Liverpool, Everton and - by the looks of things - Southampton.
Danny Welbeck will have been looking forward to this game since he left United to join Arsenal on transfer deadline day and he is in good form too.
Welbeck scored twice for England in their Euro 2016 qualifier with Slovenia last week and played very well too.
I would not say that United are missing him, because they have got so much attacking talent to choose from anyway.
But I am still surprised that Louis van Gaal let him move to Arsenal, and for only £16m.
Even if Welbeck does not score on Saturday then that decision could come back to haunt him, because Arsenal are going to get the best out of him, during the peak years of his career.
Prediction: Arsenal win (2-0)
