Wayne Rooney performed his acrobatic goal celebration against Scotland at the request of his 5-year-old son Kai.
Rooney cartwheeled away towards the England fans and punched the air after scoring his second goal in an impressive 3-1 win at Celtic Park.
"That was for my son. He's been doing them quite a lot so he wanted me to do one," the England captain revealed.
The passion was clear to see on Rooney's face as he celebrated killing off the game just two minutes after Andrew Robertson had given the Scots a glimmer of hope with his first international goal.
Rooney thinks the whole team dispelled the theory that the fixture means more to the Scots than their Auld Enemy.
"We played with a lot of desire," Rooney said. "We know the Scotland team play with a lot of passion and desire -- but there is no denying that we play with as much if not more.
"We are a proud team. We work hard for the strip and we wanted it. We expected to win. We know we are the better team, we know had to work to get the victory.
"Sometimes when results don't go the way we want, people see it as though we are not working and don't want to play for the country, but it's far from the truth."
Rooney's brace moved him above Jimmy Greaves into third in England's all-time top scorer list.
He now stands just three goals shy of Sir Bobby Charlton's record and few would back against him reaching that milestone by the end of the season.
In typically selfless fashion, Rooney deflected talk about his form and chose to praise his young team-mates for the way they have bounced back from their woeful World Cup campaign.
"The World Cup was a bad experience for us all and since that we've carried on the progression and the young lads have been brilliant," the 29-year-old said. "They've stepped up. I think if we can keep working on what we want to do I'm sure we will get better."
There was also praise for manager Roy Hodgson, who came in for criticism after leading England to a winless World Cup campaign in the summer.
"After the World Cup, Roy was under pressure, of course. We all were," Rooney said. "And he's done fantastically in how he's getting us to progress as a team. He's using all his experience which is great for us as players.
"We used a different system against Scotland to what we have in previous games, he's making us do the right things at right times in games, which is certainly benefiting us as a team."
