England made a perfect start to the tournament with a solid 6-2 win over Iran.
Gareth Southgate’s young side warned other teams with a superb performance that saw the Lions head Group B.
Harry Maguire went close as his header hit the bar before 19-year-old Jude Bellingham netted his first international goal with a glorious glancing header into the far corner.
Luke Shaw then delivered a corner that was nodded down by Maguire, allowing Bukayo Saka to strike a sumptuous volley in off the underside of the bar.
Raheem Sterling netted the third, firing home his first World Cup goal at the near post after being picked out by Harry Kane.
Saka grabbed his second goal of the match when he was played in by Sterling on the right, cut inside, and slotted home.
Iran got one back through Mehdi Taremi before substitute Marcus Rashford cut inside and coolly slotted home his first major tournament goal before Jack Grealish tapped in after being found by Callum Wilson to complete the rout.
Iran got one more back through a late penalty, but it was the Lions with the big smile of the match.
Elsewhere, two late goals saw the Netherlands beat Senegal 2-0 in their Group A opener and extend their unbeaten run in opening matches to nine.
