Tourism officials estimate that around 50,000 Scottish supporters have travelled to Greater Boston during the tournament, filling bars, neighbourhoods and local landmarks with colour and song.
Wu signed a letter of intent at a Scottish restaurant in Jamaica Plain, using the occasion to argue that the relationship should outlast the final whistle.
“This type of agreement will make sure that you always see Boston as a home base,” Wu told the crowd. “We want you to come back again and again and again.”
The proposed link would make Glasgow Boston’s latest sister city, adding to a programme that already includes 11 international partnerships.
The idea reflects football’s ability to create connections that formal diplomacy can struggle to establish. Supporters arrive for matches, but their presence can leave behind business contacts, tourism interest and personal friendships.
For Glasgow visitors, the welcome has already made the partnership feel more than symbolic. Cameron Duncan, a 22-year-old supporter, called it “a match made in heaven”. Boston resident Ada Nicodemus described the proposal as “a really cool initiative” and “super cute”.
That enthusiasm gives the plan a strong foundation, but a letter of intent is only an opening step. Its long-term value will depend on whether the two cities build regular exchanges rather than allowing the World Cup atmosphere to fade.
The partnership is expected to be formally signed next April, when Glasgow Lord Provost Jacqueline McLaren visits Boston for Tartan Day celebrations.
That will be the moment to judge whether this is simply a memorable supporter welcome or the beginning of a genuine Glasgow-Boston relationship. The next storyline to watch is whether football’s temporary community can become a permanent connection.
