The men's team were at a pool party thrown by McElhenney - a treat after they recently won the National League.

They will return to the English Football League (EFL) next season for the first time since 2008.

McElhenney tweeted a picture of himself and his wife, actress Kaitlin Olson, with the players.

He captioned it "The gang throws a pool party in Nevada for the greatest football team on Earth" - written in the style of an It's Always Sunny in Philadelphia episode title, which stars both McElhenney and Olson.

During the team's celebrations, they attended a Chain Smokers gig in Las Vegas nightclub XS.

Before the next season gets under way in the fourth tier of the English football system, the club's players will have another trip stateside.

They will play friendlies against Premier League teams Chelsea and Manchester United, and Gareth Bale's former club LA Galaxy.

"We're looking forward to our US tour as we gear up for our return to the EFL," said manager Phil Parkinson.

"We've enjoyed meeting supporters who have travelled over from America to visit us this season, and it will be a fantastic occasion to play against American opposition in front of more of these new fans."
