Luke Littler looks embarrassed as he asks official to help him with simple task seconds before final live on Sky Sports

LUKE LITTLER looked slightly embarrassed as he asked an official to help open his bottle of water.

The 17-year-old darts sensation was on route to beating Rob Cross in Liverpool when he came undone by his water cap.

Littler danced over to an official - who screwed the top off - before swigging from the bottle.

It was caught live on Sky Sports and amazingly even required a slow motion replay.

Despite the mishap, there was not bottling it in the game for teen star Littler in enemy territory.

The avid Manchester United fan was met by boos from the rival Liverpool crowd.

But Littler hit back by mocking their 2-0 derby defeat at Everton, which could effectively end their title hopes.

Littler beat Gerwyn Price 6-3 in his quarter-final opener, then stunned last week's winner Nathan Aspinall with a 6-5 comeback thriller before overcoming Cross 6-2 in the final.

The Warrington starlet's English rival briefly made him sweat in that conclusion to Prem Night 13.

At 5-0 down and facing a rare whitewash, Cross won two legs in a row.

But the Nuke took the eighth to clinch success at the M&S Bank Arena.

He then told Sky Sports of his sparring with fans: "I knew what was coming this week and I was building up to it.

"I always engage with the crowd and the semi-final I was playing with complete freedom.

"I just felt comfortable tonight. I knew what was coming and I was glad to win."
