PSV Eindhoven won their away match 2-4, after goals from Balazs Dzsudzsak, Jermain Lens, Ibrahim Afellay and Jonathan Reis.
“We want to be a quality football team, so once we took the lead, we should have shown the fighting spirit to hold on to our lead, with due respect to our opponents”, Rutten said to the club’s official website.
“We improved after the break; we were in control of the match and created chances.
“We should have scored a few more goals but we’ve bagged all three points after the international break.”
