"I have not come here for any monetary benefits. I see this job as a big challenge. I would love to see Pakistan ranked among the respectable football nations of FIFA," Roberts told a news conference in Lahore. Pakistan are ranked 162nd in the world.
The tough-tackling former England international, who won two FA Cups and a UEFA Cup with Spurs in the 1980s, will be with the Pakistan under-23 team as coaching consultant for next month's Asian Games in China.
"It has nothing to do with money. I had a chance to have an interview for two jobs in England but I want a challenge and it will be great experience for me with the Pakistani boys," Roberts said.
"We want to make a mark at the Asian Games. He has signed an initial two-month deal but if we have a good working relationship with him we will try to retain him," Hayat said.
The PFF chief said Roberts's contract had been made possible through private sponsors.
