As such, both boards agreed that October would be a more feasible time for the series to take place, ensuring that England could tour with a full-strength team rather than a second, or even third, choice squad.
The short tour is also payback for the PCB sending a team over to England during the summer, despite the COVID-19 pandemic engulfing the country.
"I know I haven't got that long left in worldwide cricket", Moeen said from the team hotel in Cape Town on England's first full day in South Africa.
The veteran added: "I think I was hungrier when I was younger, when you are trying to play Test cricket (for the first time)".
He said that we are ready to host South Africa in January-February 2021 as part of the Future Tour Program.More news: Australia alleges military carried out unlawful killings in Afghanistan
While Moeen does not believe he has many years left in worldwide cricket, he said he would like to continue playing county, franchise and even club cricket for many years yet.
Earlier on Wednesday when the tour was announced, European Central Bank chief executive officer Tom Harrison said, 'It's a significant moment for both nations'.
Harrison added that the priority would be to ensure the squad operated under the greatest security possible.
"With the COVID-19 situation being an evolving one, the PCB will continue to monitor and work with the authorities to explore ways of allowing fans to attend matches when worldwide cricket and Pakistan Super League matches are held in 2021".
He emphasized on the strong relationship the two boards enjoy.
Earlier, Pakistan toured England in 2016 (for bilateral Test series), 2017 (for Champions Trophy), 2018 (for bilateral Test series), 2019 (for World Cup) and 2020 (for bilateral Test series).More news: IO Interactive Reveals New 007 Game With Teaser Trailer
This was announced in a joint communique of the Pakistan Cricket Board (PCB) and the English Cricket Board (ECB) on Wednesday.
"I think there can't be bigger news for Pakistan cricket that England will tour Pakistan next year", he said. "I think players all over the world are missing the fans a lot".
Worldwide cricket in Pakistan was put on hold in 2009 after gunmen opened fire on the bus carrying the visiting Sri Lankan team in Lahore, killing eight people and wounding several players and officials.
"Once England tour, then confidence will grow for major teams to tour". Post the series, Eoin Morgan's men will head to India for the ICC T20 World Cup.
Earlier this year, England hosted Pakistan and the West Indies in twin Test series behind closed doors due to the raging COVID-19 pandemic, before welcoming Australia for a series of limited-overs matches.
Those series and tournaments have demonstrated the effectiveness of the high-level security arrangements put in place by the PCB, with governmental support, and proved that Pakistan is safe for teams to visit.More news: Google Pay gets major redesign; here's what has changed
