Cody Gakpo and Davy Klaassen scored late goals as Netherlands grabbed a 2-0 win over Senegal.
Gakpo headed home a beautifully weighted cross from Frenkie de Jong, before Klaassen tapped home to seal the win deep into injury time.
The Dutch are now undefeated in 16 matches under coach Louis van Gaal.
They also stretched an unbeaten record in their opening game at World Cups that dates back to 1938.
Gakpo, who has now scored three goals in his last four internationals, had their first opportunity after four minutes but tried to square the ball to Steven Bergwijn instead of going for goal.
That was followed by a Daley Blind header at the far post that flew wide before Steven Berghuis sent Bergwijn through and he laid it off for the unmarked De Jong in the box.
The midfielder took far too long to release the ball, however, and his effort was blocked.
The African champions were badly missing injured talisman Sadio Mane and did not manage a shot on target until the 65th minute when Boulaye Dia’s tried to sneak one past goalkeeper Andries Noppert, making his Dutch debut, from a tight angle.
Toothless Senegal
Senegal had a bit more possession in the second half but despite the relentless drumming from their small fan group in the stands could not find the back of the net.
To make matters worse, Cheikhou Kouyate had to be taken off injured before Gakpo snuck in to snatch the opening goal.
Klaassen made sure of the three points with a tap-in in stoppage time after Mendy palmed a Memphis Depay shot into his path.
De Jong had a chance to give the Dutch a first-half lead but was crowded out before Ismaila Sarr at the other end had a long-range shot diverted away from goal by Virgil van Dijk.
