Jack Grealish's wholesome interview about 11-year-old Finlay is already the World Cup's best moment

Jack Grealish was asked about his friendship with 11-year-old Finlay after dedicating his goal celebration in England's 6-2 win over Iran to the youngster - it's incredibly heartwarming.

The Manchester City midfielder completed England's rout after coming on for Raheem Sterling as a second-half substitute.

After finishing a fine Three Lions move, Grealish celebrated with his teammates and busted out a dance move.

Everyone quickly realised it was in tribute to a young City fan Grealish met earlier this year.

Finlay is part of City's Football Academy and sent a message to Grealish, who is his hero. Like the 27-year-old's sister, Holly, Finlay has cerebral palsy.

Grealish involves Holly in all aspects of his career and personal life, something Finlay adores.

"I wish there were more people in the world just like you who treat people with disabilities the same as anyone else," he penned.

Post-match, Grealish was asked about the celebration by BBC reporter Mike Minay.

"I've met young Finlay about a month ago," he said. "Got on, obviously, really well with him. Him obviously having cerebral palsy like my little sister as well so... he asked me to do a celebration for him. Luckily it came at the World Cup.

When asked how much it would mean to him, Grealish replied: "That's what it's all about. For me it's just doing a celebration, but that'll mean the world to him, I'm sure.

"Especially me doing it at the World Cup. Finlay, that one's for you."

Grealish then kissed his hand and put it to the camera before walking away.

Jude Bellingham opened the scoring with his first international goal just after the half hour mark with a header.

Bukayo Saka and Raheem Sterling added to England's tally before the end of the first half. Saka grabbed his second just after halftime before Mehdi Taremi scored for Iran.

Marcus Rashford scored 49 seconds after coming off the bench before Grealish's effort late on.

Taremi added another consolation in added time via the penalty spot.

England are top of Group B and return to action against the USMNT on Friday evening.
