Exactly and I support your analysis. I also think that Arsenal will probably have difficulty winning this match. But that doesn't mean Arsenal will lose, but a draw is the best choice for Arsenal not to lose points when some of their mainstay players are absent from the match.
The young player Nwaneri and the Makeshift striker Arsenal has solved some of the issues they have as a club. Unless they get injured, those two players together can deliver an attack different from what Arsenal as a club were used to, I think.
Arsenal has a good chance to win still, they have to make use of every chance they create.
