FC New York Club executives visited the world’s oldest soccer club, Sheffield FC as part of their week long fact finding visit to the U.K. Sheffield FC which was first chartered in 1857 and has been recognized by FIFA in 2007 for its 150th anniversary.

Club manager Lee Walshaw welcomed F.C. New York’s President Doug Petersen and was given a tour of the trophy room while learning the rich history of the club before exchanging kits. “It was Sheffield FC that visited New York in 1908 and toured under the name the Pilgrims of England said Walshaw” The group discussed a number of similar issues over lunch at the club owned pub located on the grounds. A return visit by “the Pilgrims” was not ruled out.

You'll hopefully forgive me for being obtuse, but how does "a return visit by “the Pilgrims” was not ruled out" constitute established ties?
