Fc Porto defense is as solid as rock but I still have believe in Arsenal to make a turn around in today's match. The good thing here is that Arsenal is playing at their home ground and we all know how strong every team is while playing at their regular play ground. The cheers from the fans and conversant ground will definitely have impacts on their performance. Bayern Munich did it last week and Arsenal can do it too, they already did in the group stage and this is the right time to repeat the history. Arsenal recent performance is really commendable, being eliminated in the UCL now will be very bad experience as they currently occupied the top spot of the domestic league table.
It's true, even though Porto does have a very strong defense, I am also sure that Arsenal as the host will be able to create gaps in Porto's defense and score at least 2 goals. Because Arsenal has recently become better at building attacks and defending. I think Arteta will create a strategy that means Porto's defense will no longer be considered strong. And the position as host always makes a team have a stronger mentality because they get support from supporters at the stadium. And it would be very difficult to believe if Arsenal failed to advance further in the UCL.
