England's forward #17 Bukayo Saka celebrates scoring his team's fourth goal during the Qatar 2022 World Cup Group B football match between England and Iran at the Khalifa International Stadium in Doha on November 21, 2022.
Playing for Birmingham in the Championship just two years ago, the Borussia Dortmund star's goal made him England's second youngest scorer at a World Cup behind Michael Owen.
Eight minutes later another of England's gifted prodigies doubled the lead.
Maguire headed down a corner and Arsenal forward Saka swivelled to lash a superb left-foot finish into the top corner.
Sterling put the result beyond doubt with his first goal at a World Cup in first-half stoppage time.
Bellingham fed Kane, whose pin-point cross was volleyed home by Sterling with the outside of his boot.
Saka made it four in the 62nd minute when he shuffled across the Iran area before stroking his shot past Hossein Hosseini.
Taremi fired into the roof of the net to reduce the deficit three minutes later.
Rashford's cool finish in the 71st minute, 49 seconds after he came on, was followed by Grealish's 90th-minute tap-in.
Taremi struck from the penalty spot with the last kick of the game after a shirt pull by John Stones, but the margin of victory reflected England's total dominance.
