Actually, the top 5 teams still have a chance to secure themselves in the UCL zone because they have a narrow point difference, only the teams are able to maintain their consistency otherwise they will lose that place. Arsenal sometimes appear impressive but sometimes also appear less impressive and are still prone to losing when facing average teams so that if Arsenal is not able to be consistent then they will lose their place in the UCL. The same thing also happens to Aston Villa and Tottenham Hotspur who are still not very impressive at all. the match they are facing. Meanwhile, Man City and Liverpool are still quite impressive and are still on the winning track.
Next week everyone will see how Aston Villa and Arsenal fare in their respective matches, although Arsenal will visit Nottingham Forest which is generally a not so strong opponent and Aston Villa will host Newcastle United which is a pretty good opponent. So both of them must be able to get a win so they can continue to maintain their respective positions and on the one hand Aston Villa must be able to score more goals so they can overtake Arsenal in the current standings.
Well, like you said, Arsenal's opponent is more weak, and for that Arsenal have a more chance of winning that encounter than their current competitor which Aston villa, though Aston villa do stand a good chance of beating Newcastle, but the fact remains that Newcastle united is not a club to be underestimated.
But all the same, I am expecting Arsenal to score more goals in their encounter with Nottingham forest, but this is if they don't end up disappointing us, because personally, I've come to believe and see Arsenal as one of the most inconsistent club in the premier league, they could disappoint when one least expect it, so, I am not gonna be all in on them beating Nottingham, but if they will, then they do stand a chance of scoring more goals than Aston villa has with Newcastle united.
