A couple of weeks ago, the F2 Freestylers happened to be in Dublin.
The duo - Jeremy Lynch and Billy Wingrove - have released a new book called Ultimate Footballer.
Essentially, it's their attempts to build the almost-perfect footballer with skills honed by some of the world's greats.
But it's on YouTube that they are huge. Their channel has 11 million subscribers and they have also made videos with some of most well-known players in the modern game, including Luis Suarez, Raheem Sterling... the list goes on.
One particularly memorable skills challenge involves Suarez. They drop a ball from a crane and expect the Barcelona striker to control it with his first touch!
That was something they discussed with Jonathan Higgins and I on Team 33 when Billy and Jeremy dropped in for a chat about the book and much more.
