Tim Cahill’s ringing endorsement for the 2022 FIFA World Cup in Qatar shows he has a tin ear. It shows that the organisers are splashing oil money at some of the sport’s most loved figures to help give their controversies a rose tinge.On his social media channels on Tuesday, Cahill, the Socceroos and Everton great, announced he had joined the likes of Samuel Eto’o, Xavi and Cafu as ambassadors for Road to 2022. The official role places him in the “Supreme Committee for Delivery & Legacy”, a wordy-yet-non-descript title that could easily have been dreamed up in the conference room of an Imperial star ship in The Empire Strikes Back.”I think joining the SC family was a natural progression for me,” Cahill said. “I’ve been travelling to Qatar since 2008, so have developed a close relationship [with the country] over the years, so to be part of it, and to share the story of Qatar 2022, is pretty special.”The public reaction was as immediate as it was predictable. This column immediately wondered: What on Earth was he thinking? Qatar 2022 has become one of the most controversial major sporting events in history and it’s still two years away.
