The teenager, fresh from winning his first senior title at the Bahrain Masters, watched the session out in the wet and windy weather and was given a signed shirt by his favourite player, Alejandro Garnacho.
He then challenged Christian Eriksen and Harry Maguire to throw a few arrows later in the day, in the warmth of the Jimmy Murphy Training Centre, with friends, family and other Reds watching on.
Unsurprisingly, Eriksen and Maguire were no match for the PDC World Championship runner-up, who was on the mark as he hit 180 during his turn at the oche.
