Full defensive is very good tactical for FC Porto on second leg match against Arsenal, get capital winning over one goal and draw result on second leg match more enough for FC Porto qualifying to quarter final although Arsenal's advantage with playing in their home. I think will make frustrated with the opponent team when FC Porto make full defensive strategies on second leg match.
I think FC Porto can take advantage with counter attack with Arsenal will play more offensive make space with their defense position, be careful for Mikel Arteta if Porto will play more defensive and Arsenal payer get frustrated how difficult scoring goals make their defense players will leave their position.
I don't think it will be a very good plan if FC Porto is going to play more of defense in the returning leg again Arsenal at Emirate Stadium, the one goal victory that Porto got is not enough to see them progress to rhe next round this is because Arsenal will come all out with a lot of pressure to see if they can get an early goal then they will push attack but once they find it difficult to score they will fall back ro defend the one goal they have while they keep pushing to ensure they get a winner goal even they it won't be an easy game for them.
Yeah, I agree; now in second leg they could be on advantage, and they need to be aggressive because if they will go for the defensive strategy then surely things can go against them, and they can lose their game with also can eliminate as well because in first leg they are already winner, and they need to be positive for the win or draw which will give them good chance but if having strategy just for the defense then surely things can go against them, and they could be on back foot with Arsenal having good attack and while playing at home they could be much better and confident for the big win which will allow them to have spot into round of 8.
