Anfield has seen some famous European nights but none compare to what it witnessed last night.Barcelona were in town carrying a 3-0 lead from the Camp Nou.Jurgen Klopp’s side needed a miracle without Roberto Firmino and Mohamed Salah.But despite the absence of their star duo, Liverpool did the unthinkable to win 4-0 and send Anfield into ecstasy.On the final whistle, the home fans erupted. The players fell to their knees almost in disbelief.

And one ball boy knew exactly how he was going to celebrate.

A video has emerged showing one very cheeky young ball boy running onto the pitch and giving Lionel Messi the two fingers.

He’s got some nerve.

The video also shows a steward chasing after the young boy. We’re not quite sure what happened next but he’s got a story to tell his kids and grandkids one day.

“I was a ball boy for Liverpool 4-0 Barcelona and ran on the pitch at full-time to swear at the greatest player to have ever played the game.”

Of course, that Liverpool ball boy isn’t the only Liverpool ball boy making headlines right now.

It’s reported that Liverpool’s match analysts noted how Barcelona players often lost concentration when the ball was out of play.

A message passed down to Carl Lancaster, a coaching mentor at the club’s Kirkby academy.

One of Lancaster’s responsibilities is the co-ordination of ball boys and he told them how it was vital to return the ball to Liverpool players as quickly as possible.

And that’s exactly what 14-year-old Oakley Cannonier did in the 79th-minute, allowing Trent Alexander-Arnold to take a quick corner-kick for Divock Origi to make it Liverpool 4-0 Barcelona.
