Khazri, 27, might not have set the Premier League alight with Sunderland last season but he sent a clear message about his match-winning ability to England, as well as Belgium and Panama who will share Group G in Russia in June.
He ran onto a ball played over his head from inside his own half, controlled it and swept past a defender before striking it against goalkeeper Keylor Navas and then getting his foot to the rebound first in the 36th minute for the only goal of the game.
The strike by Khazri, who is on loan at Stade Rennes, earned a second win in five days for Tunisia who beat Iran 1-0 at home on Friday when Costa Rica, who are in Group E with Brazil, Serbia and Switzerland, won by the same score away to Scotland.
