Dad Anthony O’Toole discovered by accident that the Kop’s song for the Dutch centre-half stops sons Alfie and Archie crying when children’s music has no effect.
And the song – to the tune of Dirty Old Town by The Pogues – is now a familiar sound in the family’s Old Swan home.
While both boys are mesmerised by the song and sights of Anfield, little Alfie looks set to be the bigger Reds fan – and can be seen in this video clapping and giving a huge smile.
Alfie and Archie were born prematurely at 27 weeks and six days after doctors discovered they had Twin to Twin Transfusion Syndrome (TTTS), a rare but life-threatening condition that affects identical twins.
Anthony, 21, and partner Lydia Moran, 19, say the twins, who are now eleven months old, have made good progress.
Life-long Liverpool fan Anthony, a delivery driver, said: “We realised they loved it when they were about five or six months old.
“I used to put the TV on before the match and they would watch it with me.
“For some reason it’s just that one song about Virgil Van Dijk – now every time they’re crying I put it on and they stop!
“As soon as the song comes on they’ll sit and watch it. When a game comes on they sit through it without a peep.
“Archie loves it but not as much as Alfie – Alfie is really into it. It’s just boss when you see him smiling and clapping as well.
“They’ll cry through CBeebies but not the Virgil Van Dijk song!”
The van Dijk song has become a hit with Liverpool FC supporters after making its debut in the Kop last autumn.
It includes the lyrics: “He’s our centre half, he’s our number four, watch him defend, and watch him score. He can pass the ball, calm as you like, he’s Virgil van Dijk, Virgil van Dijk!”
Alfie was 2lb 4 and Archie 2lb 5 at birth and spent the first nine weeks of their lives in hospital.
Anthony said: “They were tiny and even when they came home they were still so small.
“Alfie still needs oxygen and they have had their setbacks but they’re both doing well.”
Anthony has shared a video of the twins with the club and hopes it will come to the attention of their favourite player.
He added: “I’ve been a Liverpool fan all my life so they were always going to be Reds.
“Hopefully the players will see the video.”
