The players enjoyed a bit of downtime before their crunch clash against Arsenal on Saturday.
First-team regulars Dan Burn, Sean Longstaff and Harvey Barnes brushed shoulders with other darts fans as they watched Littler lose to Michael van Gerwen in the semi-final.
Team-mates Mark Gillispie, Paul Dummett, Elliot Anderson and Matt Targett were also in attendance, with the latter beaming as he watched on with interest.
Fans were quick to point out that the players had bottles of water on their table rather than beer, which they found amusing.
One reacted saying: “The English lads are out. Bottles of water all round.”
Another added: “Notice all the bottles of water 😂”
A third wrote: “Not a pint between them.”
And another joked: “Watching real world class athletes for a change!”
Van Gerwen beat Littler 6-5 in another narrow Premier League clash in Newcastle.
