I really understand that Porto's defense is very strong. At least Mikel Arteta can find a gap to score a goal in the second leg to advance to the next round. Even though Porto is in third place in the Portuguese League, that cannot be a benchmark for measuring the strength of a club. However, here you can see or find out who will be lucky in the second leg, hopefully Mikel Arteta can find Porto's weak points so they can win or turn things around.
I remember the Lens vs Arsenal match in the group phase, when the Gunners lost with a score of 2-1. however, when the match was held at the Emirates Stadiums, Arsenal slaughtered Lens with a score of 6-0. well, in the second leg something similar doesn't rule out the possibility of happening to Porto. I mean, Arsenal slaughtered Porto with a big aggregate score. well, I say this not without reason. even though Arsenal lost in the first leg at home to Porto, based on match statistics, Arsenal controlled the match, especially in the first half with 71% ball possession. so, it is possible that Arsenal will play aggressively when the first half whistle sounds. I am very sure that Arteta will not waste the opportunity when he plays with his team at the Emirates Stadium when they host Porto.
Referring to the Arsenal betting market with odds @1.27, while Porto @11.00, it is clear that there is a significant gap based on the odds for these two teams. theoretically, Arsenal should win this match on paper. however, in football it is unique. even though Arsenal is in a positive trend recently, there is no guarantee that Mikel Arteta's squad can overthrow Porto easily. moreover, Porto is ahead by 1 goal on aggregate. which means, Sergio Conceicao's team only needs a draw to qualify for the next phase. As a Gunnes fan, I hope Arsenal can beat Porto in the second leg. so, let's wait.
