Arsenal must use both a defensive and offensive strategy in their match against FC Porto tonight, or they will be defeated by FC Porto once more. I understand Arsenal will play an attacking game because they need to win tonight, but they should also come back to defend everything because if FC Porto takes the lead in this match, Arsenal will have a difficult time achieving victory. FC Porto is known for their strong defensive performance in games, so Arsenal breaking through to score an equaliser will be difficult once FC Porto have taken the lead in this match. I just want to see how tonight's match will turn out to be.
We can see that Arsenal's performance in the last few matches is quite impressive and they are quite strong on all fronts with a well-organized game, but Porto have also shown in the first leg that their tactics are able to stop or kill Arsenal's game so that it does not develop.
This will be a difficult match for Arsenal even though they will be very favourites, because Arsenal is playing at home so they should have an advantage.
