MEXICO CITY — The World Cup kicks off tomorrow with Fifa betting that the enduring appeal of the greatest footballing show on earth can rise above mounting anger at ticket prices and a US immigration crackdown that has seen fans, a top referee and team officials barred from the tournament.

A record 48 teams and millions of fans are set to descend on the United States, Canada and Mexico for the first World Cup co-hosted by three nations, the largest and most logistically complex edition of the tournament ever staged.

The action gets under way at Mexico City’s iconic Estadio Azteca on Thursday, with co-hosts Mexico taking on South Africa at 1 pm local time launching a sprawling, nearly six-week-long spectacle that will culminate in the final at New Jersey’s 82,500-seat MetLife Stadium on July 19.

Can Lionel Messi, at the age of 38, settle any lingering debate about his status as the greatest player of all time by leading Argentina to a second consecutive World Cup title?

Or can Messi’s great rival, the 41-year-old Cristiano Ronaldo, defy father time by inspiring a talented Portugal team to its maiden World Cup win?

Those questions and more will be answered over the course of a tournament that Gianni Infantino, the president of world football’s governing Fifa, has bullishly hyped as “the greatest show that the planet has ever seen.”
