Cricket-obsessed Pakistanis were Tuesday celebrating their national team's "incredible journey" to the top of the Test rankings after a turbulent seven years in which they were forced to play home matches on neutral venues.

Pakistan supplanted arch-rivals India to become the world's number one Test side on Monday, after India's final Test against the West Indies ended in a rain-hit draw at Port of Spain.

It capped a remarkable rise under captain Misbahul Haq's leadership for a team which was nearly thrown out of the international arena over a spot-fixing scandal on their tour of England in 2010.

Pakistan have also been forced to play their home matches in the United Arab Emirates since an armed attack on the Sri Lankan team bus in 2009, a significant disadvantage.

Pakistan Cricket Board (PCB) chairman Shaharyar Khan branded the rise "historic".

"The ascension to the top of the ICC Test rankings culminates an incredible journey for Pakistan cricket," he said.

"This is a historic moment in our rich Test cricket history and the credit for this great achievement goes not only to this team but to all the players, coaches and support staff members who have represented Pakistan in recent years."

New coach Mickey Arthur stressed that the work was just beginning.

"It's a fantastic achievement and a lot of people deserve the credit for that, but the top of them all will be the players who have worked hard and been outstanding," said Arthur, who coached Pakistan to a 2-2 draw in the four-Test series against England. "I am just the lucky coach who has been with the team now but others have done wonderfully well," he added, singling out his predecessor Waqar Younis.
