ST. PETERSBURG, Russia (AP) — Zlatan Ibrahimovic’s successor in Sweden’s national team did the job even without scoring the goal. Alexander Isak’s second-half performance illuminated a hitherto tough-to-watch match against Slovakia that was heading for a goalless draw until the 21-year-old striker produced a deft flick over the top of the defense. Substitute Robin Quaison collected the ball and was brought down by the goalkeeper. Emil Forsberg then converted the penalty to give the Swedes a 1-0 victory. Sweden has four points in Group E. That could be enough to advance to the round of 16. Slovakia has three points after starting with a 2-1 victory over Poland.
