Arsenal will have a strong opponent in next week's match, of course this is a big test for Arteta squad in maintaining their chances of competing with Manchester City and Liverpool. I see these three teams still have the same chance and maybe the match they play in the next match will be full of pressure to maintain their ranking.
Arsenal will play Newcastle United next at the Emirates Stadium and Arsenal knowing fully well that they were robbed the last time from a very poor decision from the VAR, will not want that to happen again. Arsenal are top to win their game following their high scoring run of goals in games, the only thing that may weaken the motivation of the players in that game is if they do not do well al all against FC Porto, and loose the game. After Newcastle, Arsenal will play against Sheffield United, that should be an easy game for them.
