Alfie Mawson saluted Jack Army members from both sides of the Pond for their phenomenal support during the Swans’ tour in America.
Paul Clement’s side spent three days in Philadelphia and a week in North Carolina as part of their preparations for the 2017-18 Premier League campaign.
The trip saw the Swans hold a number of open training sessions for the squad to meet the club’s Stateside Jacks, while fans also made the trip from Wales to cheer on the team.
And Mawson was amazed by the fantastic backing the Swans received during their games against Philadelphia Union, Richmond Kickers and North Carolina.
“The fans out in America were brilliant, especially when they shouted ‘Jack Army’,” said Mawson.
“It was crazy to see the following we had out there. It was really good to see the fans in America, and the players enjoyed the open sessions as much as the fans did.
“The Welsh fans that made their way over were great as well. It is a long trip and a lot of money - those things drive us on. It also shows they believe in us and how much Swansea means to the fans.
“I was delighted with the trip and, in particular, the support we had out there.”
The Swans, who arrived back on home soil on Monday, now focus on domestic friendly matches – starting with a trip to Championship side Birmingham City this Saturday before hosting Italian outfit Sampdoria on August 5.
