Patel, a South African of Indian origin, will succeed Malcolm Speed for the most powerful post in the sport's governing body in June.
The ICC executive board, which met in Dubai on Monday, appointed Inderjit Singh Bindra as ICC's Principal Advisor -a new role created to appease Bindra and BCCI.
According to the highly placed sources in Dubai, some of the ICC members were not 'keen' on having a septuagenerian Bindra as CEO and this was also communicated to Sharad Pawar more recently.
"In UAE, the government does not encourage the senior citizens (above 60 years) for employment and it may prove to be a great hurdle for him," the source said.
Earlier, the ICC's recruiting agency Egon Zehnder International (EZI) has shortlisted five candidates for the said post.
However, it turned out to be two-horse race as the other candidates short-listed had no major cricketing background.
Bindra-Patel arrangement was part of a compromise worked out over the last 48 hours between the BCCI and other ICC members. The BCCI had initially pushed hard for Bindra's case and the prospect of an age bar ruling out its candidate saw its president, Sharad Pawar, writing a letter to the ICC pointing out flaws in the argument.
ICC President Ray Mali and President-elect David Morgan announced the decision after the Executive Board's meeting here, saying Patel was the unanimous choice for the post by the 13-member panel.
Morgan said age was never an issue for the post of ICC CEO.
"Since we required a CEO with special skills, if Mr Bindra had been the choice, age would not have been a problem. We would have changed the rules, if need be," he told reporters.
