Pakistan's biggest city ground to a halt for several hours Sunday as fans packed restaurants and cafes to watch Islamabad United defeat defending champion Peshawar Zalmi by three wickets after being set a 148-9 target. Pakistan Super League is a big event, he added.
"You should trust me", he stated.
Fans weathered suffocating security arrangements, with 8,000 policemen and paramilitary staff guarding the venue at the various check posts in and around the stadium.
Armed soldiers were among 8000 security guards used for the event.
Their key players did not travel to Pakistan a year ago, but Peshawar Zalmi owner Javed Afridi was able to convince the rest to go to Pakistan, which helped them lift the trophy at Gaddafi Stadium in front of a packed house.
But a reluctance from some worldwide PSL players to play in Pakistan remains.
Spectators had to use a shuttle service before walking more than a kilometer to go through two security checkpoints.
The PCB has gradually convinced worldwide players to return, and Lahore hosted the first PSL final previous year, and there were Twenty20s organized against a World XI (three matches) and Sri Lanka (one).
The PSL final is seen as a major step towards reviving global cricket in the country.
However, the Pakistan Cricket Board has been trying to convince countries to begin touring Pakistan again. "It's a historic occasion as Karachi is hosting a match after a nine year gap", said Sethi before the final.
The short-form specialist played 85 one-day internationals and 32 T20 matches for New Zealand, his last a ODI against Bangladesh in Cardiff last June.
After the first 31 matches were played in Dubai and Sharjah, the PSL moved to Lahore on Tuesday, when Peshawar beat Quetta in the first eliminator and then ousted the Karachi Kings in the second.
"Pakistan is a place where I have a great connection and I feel proud that I am part of the efforts to revive global cricket in Pakistan", he said. "I simply can't describe my excitement in words, I just want the final to begin". The third edition of the PSL was launched last month with the addition of a sixth team, the Multan Sultans, more global stars, and hopeful fans eager to forget a spot-fixing scandal which tainted last year's event.
