Sweden took the lead after seven minutes when Ayari's right-footed pile-driver nestled into the far corner after goalkeeper Abdelmouhib Chamakh was caught off his line, before Isak doubled the advantage on the half-hour mark by coolly finishing a breakaway following a deft pass from Gyokeres.

Tunisia reduced the deficit two minutes before halftime through Omar Rekik's glancing header, but Gyokeres restored Sweden's two-goal cushion in the 59th minute after midfielder Ellyes Skhiri was dispossessed on the edge of the area.

Mattias Svanberg side-footed home six minutes from time and Ayari netted his second of the night with a superb strike in stoppage time to complete the rout. Sweden tops Group F on three points ahead of Japan and Netherlands, who drew 2-2 earlier.
