Arsenal first match in this competition and they will fight against PSV and this is very interesting because both teams have been met last year on Europa league and both teams have defeated each other which mean PSV can be considers as tough opponent for Arsenal especially PSV performance were increase rapidly because since July PSV has fantastic achievement and since that month PSV has through 11 matches with unbeatable status in all competitions and before they advances to the group stage PSV has been done a good job because they can able to eliminate Rangers with total aggregate 7-2 so although Arsenal is the favourite in this match but PSV cannot be underestimate because they have a potention to make Arsenal get in trouble
Although it is not right to compare last year with this year, I agree that it will be a difficult double match for both teams. PSV may have a chance in the Netherlands, but I can't imagine this Arsenal losing in England. I think Arsenal will win both games. I think Arteta will focus more on success in Europe this year.
