Really Arsenal lost this match very badly. But I didn't expect Arsenal to lose this match with PSV. But we saw PSV played very well in this match. PSV scored 2 goals in the whole match. And Arsenal didn't score a goal in the whole match. Joey Veerman scored a goal in the 55th minute of the match. And Luuk de Jong scored another goal shortly after.
Actually this is only natural, because before the match was running the two were 5 points apart in group A, Arsenal had gone through the previous 4 matches with a winning streak
And PSV is the most worthy in my opinion, it would be much more embarrassing if arsenal lost to Bodø/Glimt or Zurich.
