If you look at it statistically, the opportunity between Porto and Arsenal are still 50 50 because Porto cannot be underestimated, he is playing well in the domestic league, just like Arsenal is also performing well in the Premier League. But unfortunately Arsenal has experienced a unsatisfactory results recently, but I think Mikel Arteta already understands the team mistakes were the lack of a sharp attack line and a back line that was not good at maintaining the defense. So that it was easy for the opposing team to read to break into Arsenal defense.
Yes Arsenal need a more productive striker from now on and Mikel Arteta should have thought about this to recruit new players in the transfer market to strengthen the team performance, I thinks if Arsenal can be better than now it is possible that he can still qualify for the next round and beat Porto.
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.
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.
