Porto will try defensive tactics because they already have the advantage in the first leg. Porto can play very well with their defense. This can be seen from the first leg. But Arsenal played as host in this match. That will give them additional morale and motivation to win the match. Even though it was difficult to win the match against Brentford, I think the match against Porto will be different because Arteta will really prepare a strategy and Arsenal will go all out to win the match. I predict Arsenal will progress to the next round.
If I refer to Porto's line-up prediction in the match against Arsenal in the second leg, it looks like Sergio Conceicao will apply the same pattern and system as in the first leg match with 4-2-3-1. however, this is only a temporary prediction, it could be that Porto will implement a defensive pattern. however, as far as we know, Porto always applies an offensive pattern in every match. moreover, winning by an aggregate of 1 goal does not make them safe. so, there was no choice but to fight back during the match at Emirates Stadium, the Gunner's home ground.
In the Arsenal camp, this match will be very important and crucial. so, there is no choice but to play allout with all the abilities they have. moreover, the match was held at Arsenal's home Emirates Stadium. the Gunners should be able to overcome Porto at the Emirates, playing in front of their own supporters provides high motivation to overthrow their opponents. there is no choice but to win this match with lots of goals. so, Arteta will prepare his team when they host Porto in the second leg which will be held in the next two days.
what's unique is that the betting market is far in favor of the home team. Arsenal with odds @1.24, while Porto with @12.00. It's clear, isn't it, there's a gap between these two teams? for now, I will not assume and speculate. more precisely, when these two teams met in the second leg. however, as an Arsenal fan. obviously, we give our moral support to our favorite team.
