we see in the first leg match even though Arsenal acts as a guest at home to Porto, but the fact that Arsenal ball possession is much bigger, but Arsenal are not as fortunate as Porto and 1 aggregate point that Porto has is just a luck for me.
only by looking at the possession of the ball and the accuracy of the operand can we certainly Arsenal will win at home so that betting for Arsenal victory is much better than taking risks that are too big.
We don't need to talk about who has the most possession of the ball, this is a big league in Europe of course experience and mentality are needed, so Porto has learned more than Arsenal so the narrow victory in the first leg means Arsenal must be able to improve themselves in the second leg. , Porto is not a weak team and is easy to beat, they know how to look for opportunities to score goals and Arsenal must know that and be alert in the second leg match which will be played at the Emirates Stadium.
Arteta must be able to change his tactics a little to face Porto in the second leg so that his team will not only play more attacks and control possession of the ball but also be able to steal gaps to score goals, because if Porto plays defensively in the second leg, that will ultimately result in the result. of course Arsenal will not qualify for the next round, I would not be surprised if Porto succeeds in advancing to the next round and Arsenal must be able to convince all their supporters that they will avenge their defeat in the previous first leg match at the Emirates Stadium, at least Aesenal win 2 - 0 is enough to get them through to the next round.
