Yeah, Arsenal dominated the whole game but couldn’t score much goals. This was a very good win. Arsenal now need to ensure that they top the group to avoid unnecessary play offs from the sparks dropping out of champions League. This will ensure Arsenal safe passage through to the next round. They can guarantee a top spot group finish with a point against PSV next week.
Arsenal will surely finish top of the group, they are too strong for the other teams in that group, but i don't think Arteta is putting too much concentration to the Europa League, he can see that there is a chance now for Arsenal to win the premier league, so i think the longer the europa league competition goes, he is going to be giving few of his best players a rest when they are playing in it. But Arteta is a good manager and he bought many good players in the summer, so the club have a good depth, and every player has to perform when the club needs you, so i still feel that any player who represents Arsenal either in the premier league or europa league has to perform well, and most likely will.
