Recently, Arsenal have sometimes been unable to maintain consistency and perhaps Porto can take advantage of this to make it possible for them to beat Arsenal because if you look at the strength of these two teams, of course Arenal is much stronger than Porto.
We cannot just look at the performance or results of the two teams in their domestic league because these two teams have significant differences in competition in their domestic league.
Arsenal have really shown some signs of inconsistency lately but I don’t think they would take that to the Champions league and considering the fact that they are stronger than porto gives them more confidence to go with the intention of qualifying to the next round. Arsenal wouldn’t want to miss the opportunity of challenging for this trophy after so many years of missing out on the competition.
To compare them both in their respective domestic leagues wouldn’t justify anything, the premier league is far more competitive than the Liga portugal and Arsenal will be top of the table if they win today but will drop back to second place if Liverpool wins their match tomorrow. Porto are not playing bad either but they are 3rd place in their domestic league with few points behind league leaders. Arsenal seem more likely to win though but it will depend on their performance overall in both legs.
I think the players Arsenal have are quite capable in all their lines and they just need to maintain consistency.
I see that Arsenal players in all lines have quite capable strengths, and if we talk about the performance of Aarsnal's forwards, actually they are good, it's just that they can't maintain their best performance in every match.
Arsenal are good and playing well they just needs more blending because of some new players that joined but in no time they will be fully ready. I like their playing style and mentality, they always want to win matches no matter what and thats what a team needs. I believe in them to challenge and go far in the competition.
