A year ago, as Leicester City languished at the bottom of the Premier League and looked almost certain to be relegated back to the Championship after just one season in the top tier, you could spend a couple of hours at the club shop in central Bangkok and not see a single customer.

The rows of blue shirts remained untouched, the games playing on the large-screen TV unwatched apart from by the staff, who had little else to do. By the end of last year, it had closed down.

The club’s owner, King Power, had done its best to raise the profile, plastering Leicester merchandise all over its shops at Bangkok’s busy international airport, where it has had an effective monopoly for the past decade on the duty-free spending of the more than 50 million passengers who pass through it.
